I ordered a 2xEcho plus Gen 2 & Sub kit. All hooked up to WiFi etc, no problems.
However, issues occur when trying to create a speaker group. I can Pair echo A & B together, and I can pair Echo A with sub, but I cannot pair echo B with sub, or A+B+Sub.
It's getting quite infuriating. Obviously everything can see each other, but for some reason, only echo B & sub won't talk.
I've performed countless resets on the things, no joy.
firmware versions are identical too.
Welcome to our forum! If you've previously set up a speaker set with any of the devices in question, delete it, then create a new group. If that doesn't work, try factory resetting your devices once more, and if possible, connect them all to another network (2.4 vs 5 GHz).
