JWT App Type End-of-Life Notice: Sent in Error (?)

I have been receiving “Action Required: JWT app type end-of-life” notices that indicate, “You are receiving this message because we have identified that you are the owner, admin, or developer of a JWT app.”

My “Created Apps” list does not include any JWT apps (and to my knowledge, we never created any JWT apps.

Is it possible that Zoom has made an error when sending this e-mail notification? Is there somewhere else I should be looking to confirm this change will not impact us?
