Hi Mattias. So, the suggestion was to use the Beta firmware ( chosen from the Hub app on the phone / Tablet etc ). In order to do that, I had to reboot the phone and make sure nothing else was running, switch on the Atom, and choose. Nothing. Did it all again, and it loaded the firmware. Did a session, and it actually feels better than before. No notches, glitches, wobbliness. They have all the session details etc, but on first look, I think the beta firmware fixed all of the problems, including the tedious slowness of the bluetooth connections.It connects really quickly now, and doesn’t seem to be put off by other devices around it.
Still testing, but first impressions are good
Try the Beta option
