Version 5.21 had removed all my paired devices.

I woke up this morning with all my devices not paired to my gamin connect app, just a '+' sign.  And cannot pair any device back.

I checked the version history an apparently this version was release about 15 hours ago. So probably it auto-updated overnight causing the issure. 

I reported to Garmin support but still there is no resolution. Turn off the auto refresh on you phone setting to avoid this issue. 

Cheers
