This often happens after an iOS update, after Screen Time settings change, or when a previously hidden restriction becomes noticeable. In Zoom or Teams, it can also happen if the meeting host disables screen sharing for participants. If FaceTime screen sharing worked before and now won’t start, check whether the update finished and whether Screen Time is locked. Avoid changing many settings at once so you can undo changes easily.

It can be. Sometimes the update needs to fully complete, and some features behave oddly until the phone settles. An update can also make Screen Time restrictions show up more clearly. Start with safe checks: confirm the update finished and check Screen Time status. If the block continues in multiple apps, that points to a device restriction rather than one app.

This is almost always a settings or policy issue, not a hardware failure. Hardware problems usually show as crashes, overheating, or a phone that can’t stay connected at all. “Blocked” messages typically come from Screen Time, device management, or meeting host rules. Checking Screen Time and whether the phone is managed/supervised is a safer first step than reinstalling apps.

Often, yes. Many cases are resolved by confirming iOS is fully updated and removing restrictions (when you have the Screen Time passcode or the family manager). For Zoom/Teams, the fix may be as simple as the host allowing screen sharing. Service is usually not needed unless the phone has broader system problems. Start with safe checks before making big changes.
