I bought a second tablet to control my effects with; a Firehawk FX, a Mod Dwarf and the Eventide H9. The new tablet (Samsung Galaxy Tab A8) was also having the same keyboard issue in the Eventide app. I paired a Bluetooth keyboard to my tablet and was able to enter my login credentials just fine. It’s not ideal, but it’s a decent workaround until they get this glitch solved.
Hope this helps someone.
