HI MICROSOF I WOULD LIKE TO SAY THAT MY BING WALLPAPER IS NOT WORKING IM CHANGING BUT DOESN'T COMES YET PLS FIX IM USING FOR A MONTH

Hi, thanks for your feedback. Could you please help us troubleshoot it by : Click launcher settings → Help and feedback → Troubleshoot →Quickly Tap “Run test” on the top right corner for 10 times continuously – > Others → Wallpaper → send report? It will be very helpful.
Did Microsoft launcher is killed by system when the issue happens? Do you remember on which version the issue appeared ?
