Interesting. And you are saving and disconnecting prior to this error? Do you see this error in SmartFit or on the app once disconnected, and you are turning bt back on in your phone? I had issues when I got my new Pro 30’s because my phone still had my old original Pro’s paired and they stayed connected while un the charger. I had to go into the app settings and erace memory and cache, then uninstall, then re-install and repair to phone/app. So maybe check how many devices you have connected if this isnt a SmartFit issue. I have 4 programs active with no issues and have a S24fe.
