Excuse me?!
I DO NOT “troll” message boards.
I am a regular and active contributors here.
Virtually NO ONE here works for NOR represents Apple.
I do not work for Apple. I do not represent Apple
Virtually, everyone who posts here are just Apple product users, here, just like you.
I am sure you are going to find many other iPadOS 15 features you will NOT like or have difficulty with
I provided you with a valid link, to voice your product and concerns/issues/problem with the latest OS, DIRECTLY to Apple, itself .
Whether you choose to avail yourself of the use of this product/software feedback link to Apple, is entirely up tp you.
Good Luck to You!
