@kugiigi Thanks for asking! 😃 I know the Arrow and Touch Area of the Keyboard exsits. But I would need tap, ctrl, alt, ... more or less the keyboard modifier keys

I found a "workaround" for now:

You can get "somewhat" around the sending issue. Type enough so the "Expand Text Box Arrow" is usable (or move you finger around the text box a little (up works very often), for some reason the arrow shows up then too), press it and now you can press the blue send button to the right. It is far FAR from working / good but it works for now. That also allows selecting and then "overwriting" the current text. That can be considered as a "backspace" workaround.

ALSO: Signal-Desktop uses more battery then it should. It uses a far less if you close it and reopen it and don't open any chats. IDK. why.

I think that was a long enogth daly driver test 😃

@CatWithUT I have heard back from the person in charge of the backend of the Shop. The issue is definitely not on your end; it's caused by the Shop software being very old. It's being updated soon. In fact the migration has started and it's currently being tested.
In other words, this issue should be resolved soon. Thanks for your patience!
