iPad A2. Approximately when iOS 15.6 was installed, my keyboard (especially Microsoft SwiftKey) was made small and immovable. How to overcome this or reverse it?

1. Previously the keyboard was large and at the bottom of the screen. The target area for the keyboard was always movable. Now the keyboard is extremely small, doesn't have multiple character features, and is immovably located at the center right of the screen.

2. Many target screens are themselves completely immovable. This is particularly true of financial websites (causing increased errors and the risk of having the financial account blocked). Other websites (target areas) are movable but only by inserting 11 or 12 blank lines, which subsequently will need to be removed.

3. I complained to Apple 3 ways (phone, online, and postal mail), and they refused to help me.

4. Is there a way to restore the former keyboard situation, or at least to render the new keyboard movable on the screen, or at least to render target screens freely movable around the keyboard?
