External keyboard use with Companion text

Recently an issue has returned which I hope is an easy fix. I use Companion on an android device ( (Samsung Galaxy Tab A7 Lite SM-T225) with an external keyboard (Logitech K480). When typing messages in chat once i enter one message the cursor will then leave the message box resulting in having to touch the message box again to enter the next message. May sound simple but when you constantly have to reach to press the message box again and again it is extremely frustrating and never happened before. Whatever has changed can it be changed back please?
