Describe the bug
As much as the app functions well on NA, it doesn't react on any screens on JP. I had this same issue with the .lua code, but it could be fixed by going in the "scale" script by adding a line, here.
Screenshots
The settings.
The Skills/pref
Video
The script not starting.
Debug mode.
Same on every screens.
Device Info:
Seems like a duplicate of #259. You could try the instructions on this post and see if it helps, but like you mentioned, it might be caused by screen scaling.
@tchofy I think it's similar to #269.
FGO isn't running full-screen and isn't centred on the screen.
That's why the script isn't detecting it and doing anything.
Go to Settings > Display & brightness > More display settings > Full-Screen Display on your phone and turn it ON for FGO.
I think this should work. If it doesn't, post a screenshot of how FGO looks after turning this ON.
@MathewSachin did just that and it worked great, thanks!
