I have fixed the fly/sneak button problem where you needed to stop first before you could click these buttons. Agree that it was annoying :-) It’s all good now and will be out in 1.20.1.
I still haven’t made much progress on the corrupt background issue (see earlier post). Please keep posting if your device exhibits this problem. I may need to buy one to diagnose it :-(
Unfortunately I will have to postpone submitting 1.20 to Amazon and Microsoft for a day or two – don’t want to submit a broken version and saddle you with it for a potentially long time, hope you understand.
