Hi! I see you're experiencing black screens in all the MeWe groups you belong to and can't view or interact with them. That definitely limits your experience, so let's get it sorted out.

To start off, could you tell me if you're using the MeWe app on your Windows device through a browser or the Windows app? Also, have you noticed if this issue started happening after a recent update, or has it always been like this?

Meanwhile, here are some straightforward steps to try that often resolve black screen issues in MeWe groups:

1. Refresh the App or Browser: If you are on a browser, try refreshing the page or closing and reopening the browser. If using the app, close it completely and restart it.

2. Check for Dark Mode Settings: Sometimes the app's dark mode can cause display issues. Try switching your MeWe mode from Dark to Light if possible, then restart the app or browser.

3. Clear Cache and Cookies: If you’re on a browser, clear your cache and cookies to eliminate any corrupted data causing display problems.

4. Update the App or Browser: Ensure that your MeWe app or browser is up to date. An outdated version could lead to display bugs.

5. Check Network Connection: A slow or unstable internet connection can cause content not to load properly.

If you have already tried some of these, let me know which ones so I can suggest more targeted troubleshooting steps.

Are you currently logged into MeWe on multiple devices? Sometimes logging out and back in can refresh permissions and fix display glitches.

I'll wait for your details to guide you further!
