Hi there! I’m sorry to hear that the groups you followed disappeared after the MeWe upgrade. That sounds unusual, and I want to help you get it sorted out.

To start, could you please confirm if this issue is happening on the MeWe website in your browser or on the MeWe app on your device? Also, are you logged into the same account you used before the upgrade? Sometimes, being logged into a different account could cause this kind of issue.

In the meantime, here are a few initial steps you can try:

1. Refresh the browser or app: Sometimes a simple refreshing or restarting the app can help sync things back.

2. Log out and log back in: This can refresh your account settings and potentially restore your groups.

3. Clear cache and cookies: On Windows with WebKit browser, go to your browser’s settings and clear the cache and cookies. This can help remove old data that might be causing display issues.

Let me know what you find after these steps, and if you’d like, we can dig deeper together!
