150) Can I use Proximity App v1.x and v2.5 at the
same time?
Running dierent versions of the Proximity App
concurrently will cause the your Proximity watch to
not properly communicate with your iPhone. It is
important to only install and use the proper app for
your rmware version.
If your Proximity watch features rmware v1.0,
1.1 or 2.0, you will need to use App v1.2 to unlock
Bluetooth functionality.
If you are self-updating your rmware v2.0 to v2.5,
be sure to delete App v1.2 rst. en download App
v2.5 and update from within App v2.5.
If your Proximity watch features rmware v2.5, you
must use only Proximity App v2.5 or higher.
