Pokémon go plus

[Lucy Davies]

A friend gave me his pokemon go plus as he's uses a gotcha instead he's unpaired the go plus from his tablet. I've reset the go plus paired it with my phone via Bluetooth & paired it with my pokemon go game. Sometimes the go plus works perfectly but other times it will disconnect constantly. Any idea why this happens? To play pokemon go in using the Huawei P20 pro running Android 8.1.
