Out institution moved to the new rich content editor at the end of May. Since then, we have gotten reports from a number of faculty about a problem with the Apps tool in the new editor. Specifically, when users click into the Apps tool and then click an app to use, the box that pops up appears to either be stuck loading or is simply blank. We have most often seen this problem when attempting to embed Canvas Studio videos, but that is likely because that is the tool our faculty use most. We have had reports of the same problem happening when using the Google LTI in the Apps tool as well. Has anyone else reported seeing this problem? I have a screen capture below that demonstrates what the problem looks like. You will see that I make numerous attempts and refreshes before it finally works.
I have only seen the problem happen in Chrome so far, but I have not been able to test in other browsers much. Refreshing the browsers seems to help sometimes, but not always. I cannot reproduce the problem on demand; it appears to be very inconsistent. One of my users reported that going incognito in Chrome fixed the problem, which leads me to believe it is some kind of caching issue, but that is just a theory. In the example from the video, I am on my personal PC running Windows 10 and both Windows and Chrome are fully up to date.
I should also note that although the screen capture shows me emulating a user, I have seen this problem occur plenty of times when not emulating, so that is not the cause.
I would appreciate any input that can be provided, either on someone else who has seen this problem or ideas on potential solutions.
I am also seeing this issue with the old RCE. Clicking on an App on the toolbar results in a modal dialog with a spinning loading icon and nothing else. The page has to be refreshed a few times before the app begins to work. I have reproduced the issue on Chrome, haven't tested on other browsers.
We are also seeing this issue intermittently for some people but consistenly for one of our teachers. This is frustrating for that user and happens consistently for him in the Google and YouTube LTIs.
We too have been experiencing the same issues across all APPs available (see Plugin loading issue - July 15,2020.webm - Google Drive ) occurs with both new RCE and old. Canvas Helpdesk had us advise users to refresh cache which is a short term solution which doesn't last long.
