When it worked previously, I would use it either way.
I tried now both, case #1 and case #2. Neither works.
Not the RC nor the mobile device can see the AC.
I have exactly the same issues with my MA1 since 2 weeks. The AC just does not emit any wifi-signal, no matter the updates, beep-codes, non working QR-code, etc.
The AC does connect to and is being recognized by DJI-assistant via wire connection.
