I am completely serious.
If you feel that this expensive iPad Pro you purchased, and was really too expensive for you, doesn’t meet your needs, then sell it and find some other tablet device that has the tools you need, instead.
Other tablet makers maybe cheaper and offer everything you need.
Why suffer with a device that you clearly are NOT very happy with.
I myself, my new 2021, 12.9 inch screen iPad Pro WiFi/cellular data , 512 GBs storage model is STILL on the back order list and can’t wait to finally get mine.
This 2021 iPad Pro will be a HUUUGE hardware upgrade and step up for me from a 2015/2016, 12.9 inch screen iPad Pro WiFi/cellular data model.
Best of Luck to You!
