Only tested on a world with these specifications:
Multiplayer, I am not host, I am not OP, survival mode.
The moment I attempt to type command in chat (typing the solidus "/"), my device lags a great deal, usually freezing right away for a few seconds before it finally shows some of the text I typed (but not all of it (so it looks like I just typed random letters, I suppose)); it then proceeds to crash.
The host of the world does not suffer from this issue, and she also uses a Kindle Fire (not sure what gen though).
This was never a problem before 1.17.0
