A
Android Central Question
I have tried uninstalling and reinstalling Instagram, changing keyboards & screen/font size. App is up to date. Instagram functioned normally for me until I updated my OS to PIE.
are you using a theme? if so change it to the default one. it could be a theme issue.
If I remember correctly (not a safe bet), this problem seems to go away for some apps by forcing the Android navigation bar to be shown at the bottom of the screen.
