Hi all, i'm looking for a conclusión since my app stopped to work with USB cable last year (2023).
The message about FLAG_MUTTABLE or FLAG_IMMUTABLE appears when the app is initialized and I cannot find a solution in the community.
Black screen state if you accept the message.
In addition, I had ever read about the Arduino component never worked, so an extensión is always requiered.
Other thing that I figured out, is that if I wait for a minute after FLAG_MUTTABLE message, the app loads at least but OTG dors not work.
All posts I've read are old (2021).
Blocks are irrelevant since the error occurs even with an blocks empty project.
I think this post shows that the problem occurs with the Built-in Serial component also, but never says that extensions works well.
I confirm I always used extensions.
The thing here is to try with server test that they mention.
