iPad Mini says storage full. I've deleted tons of apps and it seems there is lots of room except for "other". Tried to update and get message back "unable to check for updates" I can't open any apps

Hello MaggieWinsor,

Welcome to Apple Support Communities. 

We understand that your iPad shows the storage is full. We are happy to help.

Were you able to complete the steps in the support article that brought you to us? We recommend using the tips here : How to check the storage on your iPhone and iPad - Apple Support

"How iOS and iPadOS optimize storage

If your device is low on storage, it automatically frees up space while installing an app, updating iOS or iPadOS, downloading music, recording videos, and more.

To make more storage available, your device may also remove items that can be downloaded again or aren't needed anymore. This includes things like apps that you don't use and the local cache for files in iCloud Drive. Your device also removes temporary files and clears the cache on your device.

If your device is almost full and can't free up space, you might get a Storage Almost Full alert. If you see this alert, check the storage recommendations or offload some less-used content like videos and apps. "

Let us know if you have further questions.

Take care.
