I noticed strange behaviour. For one of the customers we get
refresh token is invalid error. When he tries to reauthorize, it works fine for several hours/day and then the error occurs again (for the new refresh token).
I noticed that we get two different refresh tokens, so:
- token A works
- token A stops working, user reauthorizes, we get token B
- token B works for some time
- token B stops working but token A works
I can share with you details (company id, client id, refresh tokens) to looks closer at this issue.
