Hi all! We received notice that Mixpanel is ending their legacy forwarding process (US > EU server routing). This makes an existing iOS-only bug in the Flutter SDK more critical:
Bug: On iOS, group operations can silently re-create the Mixpanel instance without the configured serverURL, causing it to default back to api.mixpanel.com instead of api-eu.mixpanel.com. Previously this was masked by Mixpanel's forwarding.
Android is not affected.
