I’m not sure if I understand your issue, but I’d like to help clarify how the process currently works. You had purchased your SketchUp Pro Network Licenses and paid for the Maintenance & Support Plan which upgrades your SketchUp license to the newest version when it becomes available. We also set it up so that you have a 60-day grace period to start switching users over to SketchUp Pro 2016 from version 2015 starting when you first authorize SketchUp Pro 2016. This prevents users from having twice as many license-seats of SketchUp as they have paid for. We think it’s fair that customers are able to use the number of licenses they purchased. If, for example, someone bought 15 seats of SketchUp Pro 2015 license, they should really only be able to use 15 seats of SketchUp Pro 2016 – not 5 seats of each version. If you aren’t ready to start using 2016, your SketchUp Pro 2015 licenses will keep working until you authorize SketchUp Pro 2016. We understand that switching between versions takes time, and that’s why we implemented the 60-day transition period. Some companies want to be very careful about adopting a new version. And that’s why the 60-day transition period - where both version 2015 and 2016 can run simultaneously – doesn’t begin until a computer is authorized with the new 2016 license. Again, the transition period does not begin until the SketchUp Pro 2016 version of the license is used.
