My garmin edge 1030 can't pair to my huawei p30 pro Emui 10.0.0.178

Welcome to the problems group mate

Huawei p20, emui 9.1.0 still. Been using vivoactive3 for a year with phone and now won't maintain the connection.

Reinstalling the app helps for a day, then can't connect again. 

Same problem as you buddy

Emui 9 till yesterday didnt pair. Today I've install the Emui 10, and it still no pair

But my fénix 5 and edge 820 are paring without Any problema

Smartphone connect App settings: empty cache, restart phone, and update Connect App. This solved the issues in my case.

In the developer options there is are additional bluetooth settings. See which version of bluetooth is being used and also change the number of bluetooth devices which can connect to either maximum of 3 or minimum of 1
