Log info gets saved when closing the app.
So, for you to make it work do this:
In SketchUp, [menu] SketchUp > Quit SketchUp
(Assuming you are signed in)
You are allowed to activate two devices per seat (a subscription plan can have more than one seat), and have a spare activation (in total three allowed sign ins)
But note that each version of SketchUp counts as an activation!
So using version 2021 and 2022 on your desktop counts as two ‘sign ins’, even if it’s the same ‘device’…
If you wanna reset all sign ins, follow this procedure:
Close/Quit all versions of SketchUp on all devices.
In a browser (doesn’t matter on which machine) go to myaccount.trimble.com and sign in with the right email address ( the one that you use in SketchUp)
You should choose the account where you see the right Product ( on the left side, choose ‘My Products’)
Then click on ‘View included Apps’ and in the upper left where the SketchUp App displays you can click on ‘Manage devices’
Follow the proc and hit confirm.
The activations or sign ins are now reset!
Upon opening SketchUp, you will need to sign in again and then quit the app.
The login information is now saved and used upon starting a new file or opening etc.
Even if offline for a max period of 28 days.
When you do have internet, it will refresh the login info, provided that you close the app.
Theoretically, you should never have to sign in again, but sometimes, something is wrong with the servers and the log in info might not be right or corrupted.
Then, a sign out and back in would suffice to refresh the login info.
