Hey there,
after the recent IOS Update 13.1.3, my weather widget (Garmin pre-installed) does not get updated on my Fenix 5x PLus and also on my older Fenix 5. The connect app does react a bit strange in general regarding the location check as it uses a lot of background action as I can see in the battery info.
It seems to happen only on my iphone X, on my company phone (iphone 7) it does working the same way as ever, although the same IOS update was installed there.
On the iphone X, I simply do not get weather updates. I tried unpairing, pairing again etc., nothing helps. As it happens on two watches, it is not watch related, but strange enough, it does also not happen on the iphone 7, there everything works normal, so it seems to an issue with the Connect App and the latest IOS version on the iPhone X.
