Something not working, or a question the app does not answer? Write to us. A person reads every message.
Most messages get a reply within a day or two. Anything that needs digging into can take longer, but it does not get forgotten.
What happened, what you expected instead, your iPhone model and iOS version, and the trip code if it went wrong during a drive.
That is usually enough to find it on the first reply.
Most of what people write in about is already answered on the FAQ: why someone is missing from the convoy map, how to cancel Pro, how to delete your account, and who can see where you are.
