Swiftkey displays over apps on ios26

Hello ! I'm using Swiftkey as default keyboard on my 15 pro max and I have a problem after updating to iOS 26. When I switch to emoji and then back to keyboard, it's covering the app (like in the pic attached) and sometimes even more, like i can't see the last 2-3 rows on messenger or whatsapp.

Oh and btw, if my phone did a backup this morning, while on ios26 , can I restore it if I install ios 18.6.2 back ? Thank you!
