Receiving ExtensionError when renewing mail subscriptions using Graph API for existing valid subscriptions

问题

We're using the following to renew mail subscriptions using an app-level access token (have been doing so for a while now).

PATCH https://graph.microsoft.com/v1.0/{subscriptionId}

Lately, this request started failing sporadically, for valid subscriptions, with the following error:

ExtensionError - Operation: Update; Exception: [Status Code: NotFound; Reason: Not Found]

For example, the following ID failed to renew efea31ea-4ff4-4199-8f68-78ec0462797d even though its expiry is the next day.

For this same mailbox, a new subscription is successfully created after failing to renew the existing one. The mailbox seems to exist and can be queries using the Graph API.

This issue seems to be about the subscription, not the mailbox.

These errors seems to have started last month, so fairly recent. Anyone encountered these or is aware of any existing issue with renewing subscriptions using the Graph API?

Thanks!
