Hi, first of all, much thanks for such super IDE
Its tiny, but no less than rocket in pocket
I migrated my signage system from kotlin to b4a
and development pace yet shoot up
I had challenge, to keep app running 24h
I'm using auto restart code (by @OliverA
)
with little help from gpt
My tester says same apk running fine on android 8
But close on android 11
Both are android boxes
