I'm running on an up to date 64 bit version of Windows 11. There is no Settings>Update & Security. There are now two Settings: one is Privacy & Security and the other is Windows Update. In neither of those do I find any Troubleshoot option. When I try to update my installed TikTok web app (which I installed from the Microsoft Store a long time ago), I get "there has been an error. See details." Clicking on the details link I get a modal popup dialog that reads "Wait a few minutes and try again The update failed Code 0x80073CF3
I've waited and retried for a long time with no change in the results. I've restarted and the same result. I don't need to sign out, because when I come back after a reboot I'm always required to sign in again. Resetting the store cache doesn't help either. I also tried disabling my AV (including Windows Defender and Firewall). None of those attempts made any difference. I still get the same error and code.
