Hello,
I have a mix of 1st and 2nd gen Echo’s. That said, when connected to my 2nd gen Echo’s via Bluetooth from my iPhone X and streaming and surfing the web at the same time over Wi-Fi, the Bluetooth breaks up horribly. When doing the same with my first gen Echo’s, there is zero break up or interference. Since this occurs on multiple Echo’s, I feel safe ruling out a hardware or software issue. Has anyone else experienced this?
