Just tried posting and backspace fucks it up as well.Latest Chrome Stable (85.0.4183.81) Tried with SwiftKey, Gboard and Samsung Keyboard. Got two other members of my board to verify. Checked here and happens here as well. While trying to respond in a thread... Keyboard disappears as soon as you press enter. End result is that you end up...xenforo.com
Looks like an issue with mobile browsers unfortunately.
