Extension warehouse issues with purchased extensions

I need help with resetting all my SketchUp licenses FOR extensions. All of them have reached the activation limit, but some of these activations are associated with old or unused devices.

@colin I’m having the same issue. Upgraded to SU2024 and now I can’t use the Eneroth Slicer plugin because it says 6/6 activations used. I went back in to SU 2021, 2022, and 2023 and disabled and uninstalled all plugins and nothing changed after signing out and back in. Can you please help? Thanks

I could see the problem, it should work now. If you’re still using Profile Builder 2, that also would have had a problem.

Thank you! that worked. Is there a way to keep this from happening when I upgrade to new versions in the future? Uninstalling or disabling through the extension manager does not seem to affect activations
