Edit: Update to the below, but leaving it posted as there is an issue that needs to be looked at. When I tried to add icons to Start11 the app crashed and service restarted and then all my tiles reappeared, so that's solved it.
Just installed the update via the app update, and now all my Windows 10 icons have vanished the panel is blank as in screenshot.
Where are these saved so I can restore as it's a pain to re-organise and remember what was there.
Even the Windows Menu icon is gone, how do I get that back so I can view the Windows 11 start menu. Do I have to add everything to the panel manually again and what will stop this happening at the next update, so can you send me instructions of how I can back this up, I'll take a screenshot too so I can re-org the way I want.
