Permanent Blue LED

OnePlus 8T, Sony Head Unit, FW1.90

Hello,

The Carsifi was working fine, but now I have a permanent blue LED out of a sudden.

Can anyone help with that?

I have the same issue, no response from any actions on the adapter ( disconnect cable-reconnect, reset adapter by clock and hold when connected to AA USB, 15 clicks to factory reset connected to non-AA USB).
Have you found a solution other than replacing the whole adapter?
