License Sketchup Pro 2021

Hello, I need help! A year ago we used sketchup pro services, we had six licenses, but with the demand for projects we bought one more now in January. Our problem is that we can’t connect all accounts at the same time and we need a lot. Some connect and others don’t, appearing the following message when we log in: Authorize SketchUp You’re using SketchUp Pro on many machines.
Log out on another machine or manage your activations below.
Manage activations We’ve done everything to normalize the situation, but we can not, help us!!

If you’re an ‘admin’ (eg. the email that bought) you need to assihn ‘seats’ to the endusers by adding members in the accountportal of the admin.
