@[deleted] pointed out the solution in the other topic. So if anyone facing the same issue, here’s the solution.
Kindly add the
batocera-boot.conf. It works!
Explanation: It’s a 30 seconds pause before the Batocera will mount the network folders and it’s enough time to establish WiFi connection.
EDIT: After start the Raspberry it doesn’t work. The solution is reboot Batocera from main menu. After 2nd attempt, it works.
