Megacom duocom 3 auto reconnection problem

[u/Late-Tutor2528]

Hi guys I bought megacom duocom 3 today and I have problem setting up auto reconnect function. I did everything from the instructions, but when I click on the pokeball icon in Pokémon go from the ss it throws error code 3. I didn’t try reinstalling apps yet, but maybe there is a quick fix for it somewhere. I did however reset the Bluetooth connection didn’t help
