DNS: check the resolution path first
DNS resolves domain names to addresses. Review the DNS options in Settings, and check whether the active Config includes its own DNS settings so you don’t overlook the effect of changing only one location. Keep settings that already work. Change them only when you have a specific reason, such as failed resolution, unexpected addresses, or a need to use a particular resolution path.
Custom DNS and DNS over HTTPS both require an accessible resolver and aren’t automatically better than system DNS on every network. Change one variable at a time, reconnect, and access the same target again. Then review the resolution results to see whether anything improved. Using DoH doesn’t mean all requests automatically go through a proxy; check the DNS path and the connection path to the destination separately.
Test Method: use consistent testing conditions
Find Test Method in Settings, choose an option available in the current interface that suits your network, then return to Home and run Connectivity Test. Different methods check different things, so their timing results aren’t directly comparable. If the test requires a target address, first confirm that the target itself is accessible, then compare servers.
A successful test doesn’t mean every service is accessible, and a timeout doesn’t prove the entire connection is unusable. To compare servers, keep the test method, target, and local network the same, and verify results with actual requests. The order of the results reflects the test at that moment, not long-term performance.
Today Widget: quick access and status
Today Widget options configure the quick-view or action features provided by the system. First check which features the app supports in Settings, then add them where the system allows. Available formats depend on the system environment, so check what appears on your device rather than assuming every device has the same layout.
Quick access can reduce the steps needed to reopen the app, but after setting it up, return to Home to confirm the server, Global Routing mode, and connection status. If the widget and in-app status don’t match temporarily, open the app and check again before changing server details. Verify separately that the connection is active and that the target request works.
iCloud: sync scope and recovery order
Check the iCloud sync or backup options in Settings. Read which items are included in the current interface before deciding whether to enable them. Syncing configuration is not the same as restoring a purchase; app access and restoring purchases are handled through the App Store. Don’t assume system permissions or the current connection state will be fully copied between devices along with files.
Before enabling sync, save existing local configurations, especially if you’ve made changes on both devices. After restoring, check subscriptions, the selected server, and the active Config one by one, then test the connection manually. Treat content containing subscription links or authentication fields as sensitive. Sync convenience doesn’t replace checking what the backup contains and covers.
Diagnostics: gather information about a specific issue
Diagnostics lets you view or run the diagnostic checks available in the app. Look for the relevant options in Settings. First identify where the problem occurs: subscription update, connection setup, domain resolution, or a request to a particular destination. Note the current network, mode, and sequence of actions before running checks related to the issue.
Change one setting at a time, reproduce the issue, and compare the results. Diagnostic data may contain addresses, domains, request details, or authentication information. Review it and remove sensitive details before sharing. Diagnostics provide clues, not guaranteed fixes. If local settings match your existing details, continue checking the server-side configuration and the destination service’s availability.
