@Marek If your Apple services are acting up, check their official System Status page or a tracker like StatusGator first. It’ll tell you instantly if there’s a widespread outage.
If everything appears fine but you're still having trouble, the problem is likely with your device or account. In that case, you should contact support.
Quick Check Resources:
Apple Official: The System Status Page is the most accurate for iCloud, iMessage, and App Store outages.
Third-Party Trackers: Sites like DownDetector or IsDown often catch local or regional spikes before Apple officially updates its dashboard.
The "Airplane Mode" Trick: If the status page says things are fine, try toggling Airplane Mode or restarting; it often forces a fresh connection to the server.
