New Browning BTC-4G RLDC fails LTE test?

[Boll Weevil]

I've been going back and forth with Browning c. service and still can't get these cams up. I have 4 of the older models, they added to subscription with ease and have worked flawlessly ever since. At first they said try a different SD card (Browning, Kingston, or SanDisk)...no dice. Failed LTE test. Tried to set'em up in the timber, in open fields, at the farmhouse, at the househouse...nada. Just sent Browning another note; I may be swapping these out for the old model if this doesn't pan out.

Anyone got one of these and seen a similar issue? Got a fix?

For others that might have this issue, Browning says software update needed. Instructions here.
