We are facing a similar issue with Exact Online that a user has described in the past. The solution for the problem was created in a Pull Request, but not Merged:
We are now facing a client that receives errors in almost every flow due to this mechanism. Exact has given us special treatment to have less restrictions around the re-use of old tokens, but only till 1-9-2021, then the normal rules will hold again.
Furthermore, it looks like the Teamleader (www.teamleader.eu) API has the same problem, the second request always fails when we start a data extract that has pagination. My request: could the Pull Request be looked into and perhaps be appended to the upcoming release?
We have some other big changes coming and would like to release a single breaking change to avoid having our users go through multiple breaking versions.
I cannot say exactly when we can release those changes as some of them are still in progress but we are working as fast as possible to release.
