Hello @Trishutcheson
Thank you for contacting the Canvas Community. We're sorry to hear you've been experiencing issues with Google and other external apps. Do the assignments or links open at all? Is this specifically affecting you as a teacher or students or both? Typically, there are a few things students and you can do to fix Google LTI:
1. Open https://www.google.com and ensure multiple Google accounts are not signed in on the browser
1.1 Signed in accounts can be seen by clicking on the profile image in the top right corner of the page
1.2 If there are multiple accounts, sign out of all accounts and then sign into only the one that should have access to Google Drive
2. Ensure third-party cookies are allowed in the browser
2.1. Chrome - Follow the steps under "Change your cookie settings" - "Allow or block cookies" and select the option "Allow all cookies"
https://support.google.com/chrome/answer/95647
2.2. Firefox - Follow the steps under the "Disable third-party cookies" heading. After step 3, uncheck the Cookies option and click the Reload All Tabs button
https://support.mozilla.org/en-US/kb/disable-third-party-cookies
2.3. Safari - Follow the steps to open Privacy settings and uncheck "Prevent cross-site tracking" and "Block all cookies"
https://support.apple.com/guide/safari/manage-cookies-and-website-data-sfri11471/mac
2.4. Edge - Follow the first line under the "How to manage your privacy settings in Microsoft Edge" heading. Choose Balanced under "Tracking prevention"
https://support.microsoft.com/en-us/help/4468242/microsoft-edge-browsing-data-and-privacy
3. Disable all extensions/add-ons in the browser
4. Check that the browser is up-to-date and if not, update the browser
5. Clear the browser's cache and cookies
5.1. Chrome - https://support.google.com/accounts/answer/32050
5.2. Edge - https://support.microsoft.com/en-us/help/4027947/microsoft-edge-delete-cookies
5.3. Firefox - https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox
5.4.1. Safari - https://support.apple.com/guide/safari/clear-your-browsing-history-sfri47acf5d6/mac
5.4.2. Safari - https://support.apple.com/guide/safari/manage-cookies-and-website-data-sfri11471/13.0/mac/10.15
6. If you do not see the items referenced in the next steps, skip that step:
6.1. Log into Canvas and navigate to your user settings page by clicking Account - Settings
6.2. Scroll down under Approved Integrations and click the trash icon next to "Google Drive LTI IAD-Prod"
6.3. On the message "Are you sure you want to delete this access key?" click the OK button
6.4. Hover over Google Drive under Registered Services and click the X icon
6.5. On the message "Are you sure you want to unregister this service?" click the OK button
6.6. Remove Canvas token(s) from your Google account
6.6.1. Log into Google and navigate to Security - "Third-party apps with account access" - click "Manage third-party access" (https://myaccount.google.com/permissions)
6.6.2. If "Canvas" or "Google Drive LTI by Canvas" are listed, click on the entry to expand it, click the REMOVE ACCESS button, and click OK on the "Remove access?" prompt. If there are multiple listed, do this for each one
7. Open an incognito/private browsing window and log into Canvas
7.1. Chrome Incognito mode - https://support.google.com/chrome/answer/95464
7.2. Edge InPrivate window - https://support.microsoft.com/en-us/microsoft-edge/browse-inprivate-in-microsoft-edge-e6f47704-340c-...
7.3. Firefox Private Window - https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history#w_how-do-i-open-a-...
7.4. Safari Private Browsing window - https://support.apple.com/guide/safari/use-private-browsing-ibrw1069/mac
8. Navigate to your user settings page by clicking Account - Settings
9. Click the Google Drive button below Other Services, then click the Authorize Google Drive Access button
10. Follow the prompts to sign into your Google Account to complete the registration
11. A green message "Google Drive account successfully added!" will be shown at the top of your User Settings page
Once these steps have been completed and Google Drive is shown under Registered Services with the correct email address, log into Canvas through an incognito/private browser window, navigate to where the tool was giving you trouble and see if the problem has been resolved. If you still experience the same issue, please record a screencast going through all of the steps above and ending with the error shown and we can investigate this further.
If none of that works, you may need to contact the school as Canvas' visibility on Google LTI integration is limited to just our website and not Google.
Because of the complexity of the issue, and the concerns for privacy, it would be best if you contacted Canvas Support directly to pinpoint the source of the issue and provide a resolution:
