Be advised that your iPad storage is close the “higher end ” minimum free, internal data storsge that needs to be maintained for your iPad to work at a nominal, acceptable level of device performance.
A 32 GBs storage iPad starts out with approx 30 GBs.,after initial internal flash drive formatting.
Minus approx. 6.5 GBs for iOS/iPadOS leaves between 23-24 GBs.
Minus 3-6GBs, for iOS/iPadOS system operational reserve, that MUST BE MAINTAINED AT ALL TIMES, to ensure/insure normal, expected operation of iOS/iPad OS, leaves approx. between 18-20 GBs of actual, usable data storage space.
Your iPad has approx. another 8-10 GBs left of usable internal dats storage space.
You should never, EVER completely fill up ANY computer and computing device with dats.
Good Luck to You!
