If you’ve tried transferring Pokemon from Pokemon GO to Pokemon Let’s Go recently, you may have experienced some connectivity issues.
Apparently, a recent update to the Nintendo Switch has affected its ability to sync with mobile phones. Niantic has investigated the problem, and is now advising players to reboot their Nintendo Switch consoles completely before linking the two games again.
Trainers, we have confirmed that the latest update to the Nintendo Switch is affecting the ability to connect to Pokémon GO. Disconnecting Pokémon GO and restarting your Switch by holding the power button for 3 seconds should allow you to reconnect.

According to several Reddit discussions, players might also need to further disconnect other bluetooth devices from their phones first.
In any case, let’s hope this doesn’t become a recurring issue with every Switch firmware update.
