Automatic rotation / landscape mode

I have a T865 which is landscape orientated and the turn button appears on the right down side when navigating. It’s a nervous button appearing and disappearing. It is also close to the three dot option button when you wear gloves. I pressed it once by accident and it did flip. However in the portrait mode the button was gone and I could not get it back to normal again. Only removing and re installing the app solved the issue. Quite frustrating.
Is this a known issue?

I would like the option not to display this button anyway as I will never use this option. Also the other buttons being sizeable would be nice!
