I have an Apple Watch Series 3 with LTE, I activated an LTE plan with it, and it looks like none of the 3rd-party apps I installed on the Watch has any access to LTE data. The Apple build-in apps have no issue accessing LTE at all.
Is there something that I'm missing? Are 3rd-party apps blocked by Rogers from accessing LTE data?
Re: Apple Watch LTE: 3rd-party apps can't get data?
I found a way to fix it. I unpaired the Watch, then on the iPhone I went to Settings, General, Information, and was prompted about a cellular operator update. After that I paired the watch, installed a few 3rd-party apps, and they worked over LTE.
The odd thing is that the operator version on the iPhone remained the same (33.1). I suspect "behind the scenes" there was an update to the Watch operator profile (5.1), though I didn't note down that version before unpairing/repairing.
