Connect IQ issues? Forerunner 55 not connected to app.

I saw the apple App Store comment stating the same, that their Garmin forerunner 55 doesn’t connect to the IQ app but it’s connected to the connect app. I tried everything from uninstalling the all, removing the device then adding it back on, restarting phone and watch and it’s still not connecting to the IQ app, similar with my backup 235, 245 and 45. Anyone experiencing the same? Could this be an issues I bought these watches second hand? They were all working a week ago and now none connect to the IQ app, possible app update issues?
