I think you need to check a few things... so this springs to mind:

1. are you creating projects with a "ProjectTM"?  If so you would be updating this and then possibly checking your Main TM which won't be updated until you Finalize or run a batch task to update the Main TM.
2. are your TMs stored in a network location... OneDrive, Dropbox, MAC file system etc.?  Could be that these TMs are not really accessible even though you think they are.
3. bit of a basic one... but have you got your TM's configured correctly in your project settings and not just your File Options?
4. are you sure you are checking the same TM you are updating?  Have you checked the paths?
5. another basic one... how do you know they are not updating?  What are you checking?  If you re checking in the TM Maintenance View are you aware this is paginated after to exceed the default TU's per page you won't see new TU's unless you navigate to the next page.

Thank you Paul,
everything in my work routine remained the same, the only thing that changed was the update to SR2.
I therefore decided to re-install the SR1 and everything seems to be working fine, tm's are being updated. Might try to install the SR2 sometime later, when no urgent projects are pending.
Thanks again - Lucie
