Even if your iPad apps are “dark” or missing – or your iPad is broken – you can still access the LMS, use Google Meet, access Google Drive, and even check your email by using a web browser [Safari, Chrome, or Firefox, for example].
If nothing has changed, then do the “iPad Reboot Dance“:
Swipe out of all your running apps,
then press AND HOLD the power button on the top of your iPad.
Swipe to turn it off.
Wait 2 minutes, and power it back on.
THEN plugin your iPad and wait a while, to see if anything changes.
Try clicking on one of the dark apps – sometimes that gets the install process kickstarted.
If NOTHING works, then send an email to IPAD – listing what apps are dark.
