After flying from US back to my home in Canada all my Apps that are always on my various home screens have just disappeared.
It's never happened before. All the Apps are still in the full App menu but just nothing on the 5 home screens I typically scroll thru. I am just strolling completely blank screens other than the top bar showing notices and time and connections.
If you have a full backup of your phone from after arranging your screens the way you had them resetting your phone and restoring from backup should put the apps back as you had them but you will have to set up and sign into each app again so takes some time and also save any data you have on your phone since the backup cause you will lose it otherwise
Iknow this doesn't help now but in the future it might not hurt to LONG PRESS a blank spot on the homescreen, then pick home screen settings and LOCK THE HOMEPAGE LAYOUT, you will hafta change this if you want to fixer up at any time, but then put it back on. 🤷♂️
