@zdenek @Mykle1 For me, it’s the same error on iPhone and Android. I think the phones turn off WiFi or use some energy saving mode because they log on and off all the time when they are passive/inactive, When I keep the screen ON, they are visible all the time. Therefore, the “KeepAlive” is a “must have”.
Now that I use early Februray, it works better, the phones only log off sometimes when inactive.
But I would really like to hide devices that are not logged in, so you can add other friends and family who do not need to be visible all the time.
