Bluetooth problems

i just upgraded my Fenix 3 to Fenix 5X. On my Fenix 3 I have never had any issues regarding Bluetooth, but my new Fenix 5 connect and disconnect all the time. It is impossible to setup settings for my iq apps, because when it disconnect, I have to start all over.
I can see that there have been other issues regarding Bluetooth, but Is the issue resolved?
