Screen reader + OCR


On samsung tab s6 lite android 10. Pleco 3.2.84 :
In landscape mode the screen reader + OCR green window is stuck to bottom making the select character forward/back bottoms hidden and thus unusable. Very inconvenient since this is normal mode. Portrait mode works normally. This problem persists after reinstall. Is it possible to reinstall an early version of pleco which would again allow screen reader to work in landscape mode? Where can I get a link to earlier versions of pleco.
Before pleco upgrades, my tab s6 screen reader worked perfectly.
