I also recommend going to Amazon. I purchased a clear cover they were selling for $9.95 and it's great. I also have the smart keyboard from Apple and the cover does not interfere with the keyboard.
I tried looking for a "front" smart cover for Ipad pro 10.5 (non apple brand) and i cant find any. I saw cases that includes back and front cover attached to each other together.
Is there a non apple brand smart cover for 10.5 ipad pro?
