Sync problem with Garmin connect android mobile app after app update

My android mobile update it self to ver 4.5 today and since, there is a sync issue with my 5x. Now the mobile app shows that it has connected with the Fenix 5 and appears to sync but the Fenix 5x shows a status of waiting for phone. Now up to today it has been working perfectly, it has only mucked up after the mobile updated to ver 4.5. Not sure where the problem is, with the mobile or the Fenix 5x.
