Is this a one-time issue or a repeatable issue?

Hi, thanks for the report and sorry for the late reply.

Per our documentation, only a single instance of MapboxNavigationProvider should be active at a time. The error you’re seeing usually happens when a previous navigation session hasn’t been fully released before starting a new one.

Could you please share a small code snippet that shows how you start and dismiss navigation and reproduces the issue?
