Anyone had a problem connection to Nextbase app for 622gw. Have gone back to default settings on Nextbase, installed uninstall app to start from scratch but doe not pair to phone.
I have the 522GW, and if I get an issue similar to yours, I flush the cache and data from SETTINGS/APPS/MYNEXTBASE, then re-pair the dashcam with my Note 9. I think the issue is with MYNEXTBASE, not your phone.
