Teachers from multiple schools in our district have submitted support tickets that when using the stylus to give feedback in iOS Speedgrader, the pen will work for a time but then will lose functionality and begin moving the document around on the page. We have a video of this issue File_000.mov - Google Drive
Support has escalated the issue, but haven't been able to recreate. Is anyone else experiencing this or know why it might be happening? All of the users are on iOS 10 with the most recent versions of the Canvas and Speedgrader apps. The 4-finger/3-tap method of clearing cache in iOS Canvas doesn't seem to work in iOS Speedgrader.
Thanks in advance for your feedback!
