Hi,
Sorry to hear you are still having trouble. Is it just the Store app that is not updating or are other apps also having trouble? Here is what I suggest trying:
Run the troubleshooter:
Select the Start button, and then select Settings > Update & Security > Troubleshoot, and then from the list select
Windows Store apps > Run the troubleshooter.
If that doesn't work try resetting the Store:
Select the Start button, and then select Settings > Apps and then from the list select
Microsoft Store > Advanced Options > Reset
More suggestions -> Fix problems with apps from Microsoft Store
Hope this helps,
Greg
Running the troubleshooter says "Troubleshooting couldn't identify the problem".
When I try "Select the Start button, and then select Settings > Apps and then from the list select
Microsoft Store > Advanced Options > Reset", it looks like it is doing something, and shows that the Microsoft Store app was "Modified moments ago", but it is still
version 11906.1001.18.0.
I have installed other apps from the store, but have been trying to get out of S mode and since the fix for that is to get the new version of the Microsoft Store app, that has been my primary issue.
I have also noticed several other people reporting they are having the same issue of not being able to get the fix.
