I am stuck on version 13.5 of After Effects when I know that the latest version is 13.7. I have tried uninstalling and reinstalling all of my adobe apps. I updated my Mac. And I re-downloaded the Cloud app.
None of those things have worked, and I'm still stuck in an old version when Adobe tells me I am "Up to date".
Try the Adobe CC Cleaner tool after you uninstall to clear all of your Adobe stuff off the system.
