QuoteThis error (0x80246002) happens if you delete update(s) from WSUS after that update(s) was already downloaded into a deployment package in SCCM then you attempt to republish it and deploy it again in SCCM.
Yes, this was exactly the cause. I realised after I had done this that I had messed up, but couldn't figure out a way out of the issue.
QuoteWe are planning to release a new update (Version 1.2.3) to our publishing service either tomorrow (February 20, 2019) or Thursday.
Nice timing. This mostly seems to fix the issue (I can republish applications fine) however I'm finding that the Patch My PC application frequently forgets the products I've selected, particularly after I make any changes. The application will show the products after I sync them, but the sync log shows nothing is synchronised and if I re-open the application, all the applications have been unchecked. This has happened both with the beta (1.2.3) and production (1.2.2) versions. It's the third or fourth time it's happened since I first installed the application a couple of days ago.
