In order to keep Trados Studio activated with a Subscription license, please update to Trados Studio 2024 CU1 as this issue was addressed.
You can switch to a different Trados Cloud/Team/Accelerate/Enterprise account and still keep Trados Studio 2024 activated.
Changes to accessing shared cloud resources with a subscription license
Previously, when using a subscription license, you couldn’t select another cloud account for doing translation work and use its resources. You might have seen that you activated a subscription license but it wasn’t possible to select a different cloud account. Now, with the new mechanism you can freely select other accounts where you have been assigned translation work. (LPB-6171)
