"Family sharing: I’m in a shared family storage plan, but it’s still saying I have no storage space on my iPad but there’s still 2TB of storage? I’m not sure if I did something wrong while joining. I already signed out then signed back in, but it’s still not letting me use the storage plan, there are only 3 other people in the family storage."

Troubleshooting iPad Storage:
Internal storage cannot be upgraded. It is what it is. So, the maximum internal storage capacity never increases, even if you upgraded your iCloud plan. Learn More here: What's the Difference Between Device Storage and iCloud Storage? Apple Support.
So, what to do:
Clear Space:
Having little empty space can heat things up. So, here is what to perform...
A. Clear Temporary Internet Files:
Clear your Temporary Internet Files(Cookies & Cache) of Safari:
Also...
B. Clean TV and Music Libraries:
Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.
Also...
C. Clear "Other":
Clear the storage named System Data (formerly called "Other"). It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time. Perform the same as instructed here, but on your iPad.: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tip. Caches would be being used for remembrance of application use.
