I found a solution but it will only work if you downgrade. I have tested 2 ipads and it fixed the issues. Google search downgrade from ios 13 for more detailed info, download the firmware 12.4 for your iPad model, sign out of the cloud and find my iphone app, then plug your ipad into the computer (I am on a PC, not sure about a mac) hit restore and hold the shift key at the same time, you can then choose the ISPW file you downloaded and it will downgrade you. I tested a 9.7" pro and an 6th gen and both are working fine after downgrade. Apple only signs the old software for about 30 days so do it soon. Hope this helps others.
If you search for this "iOS 12.4.1 Restore Images" you will find the firmware. I am not sure if I am allowed to link it or not.
Testing Air 2 is not working like the others, I am getting stuck on activation. Possibly Apple stopped signing will update. Hard reboot fixed the stuck on activation on the Air 2.
