For the Progress Learning issue, when this happens it is almost always because the student is not doing things the correct way (not necessarily on purpose, they just might not realize there is a proper and wrong way).
Have them do the steps below (but make sure to watch them to ensure they are following the steps correctly, students are silly and/or sneaky and will say they did it correctly when in fact they did not, lol)
Follow these correct steps:
Have a student who is having the issue restart their device. Watch them do this.
Then have the log back in, and while watching there screen while it loads, if a message pops up saying something about "Welcome Recap, Open yiur previous windows and apps. No thanks Open"
They should always say "no thanks"
Then they should open chrome, go to bookmarks folder FIRST and click on Clever login.
Then they click on Login with Google and ifnit asks they select their hpa Google account.
After that, then they click on progress learning. It should load correctly, although sometimes it might take a few seconds to fully load.
When a student follows the exact process above, let me know what happens. This will help narrow down any further steps needed.
