This was happening to me too when the tokens expired after an hour. I realised that it wasn't getting a refresh_token within the token itself. After googling and going through the source code, I found out that you have to pass offline_access inside the scope otherwise a refresh_token won't be returned.

• pymstodo/client.py

class ToDoConnection:
...
_scope: str = 'openid Tasks.ReadWrite offline_access'
...

After the change above, I got a refresh_token. I still need to wait an hour to check if it refreshes correctly but I'd imagine so. So yeah... Thought I'd post this here whilst I wait. I'll edit this comment otherwise.

Sorry for ignoring, just reverted the scope to openid Tasks.ReadWrite offline_access.
