Is anybody able to get detailed weather glance in 1520 with windows 10 similar to what we had at 8.1? I mean full wather glance not jsut one line glance as we see now.
No weather apps are capable in WM10 to show any sort of information on the lock screen Glance similar to 8.1 (Glance 2.0). This is because Microsoft hasn't opened up the API to 3rd party developers neither have they updated their own apps to take advantage of it.
Just tested one of the apps (at random) I've listed in post#2, now it's showing lock screen information as my lock screen background image provider in my L1020 running W10M. I must mention, though, that these apps that "work" are the same apps that worked in WP8.1. If the OP is looking for "new" or those "built for Windows 10" weather apps, then none of those "new" ones provide lock screen information. However, those that were in WP8.1
Do any of those apps show up on Glance screen? That's what the OP is asking.
