Package Manager not showing most recent updates of packages in project

Using Unity 2020.1.17f1 on a Mac Pro. My Package Manager does not show the most recent versions of packages. For example, In Project, the latest available update for In App Purchasing is 2.2.1. However, in "My Assets", the latest version of Unity IAP is 2.2.5. When I click Import, the import process runs. However, the IAP version in project remains at 2.2.1, and no higher versions are available. I think there is something wrong with my Package Manager, as it also does not show some of my external packages at all, (eg EasyMobile Pro), even though these are installed. Is there a way to fix the Package Manager?

 

I'm having the exact same issue. Did you get it to work somehow?

 

Apologies for the late reply - no I didn't, and I haven't had a response from Unity. The packages do appear to be in the project but they don't show up in the Package Manager (or else old versions appear in the PM). It hasn't yet broken my game but I'm concerned that it might

 

I've resorted to using the manifest.json file. It does the trick although it's a little less userfriendly.
