After an update, the interface still looks as it did before.	Reload with Ctrl+F5 and check the service status.
The interface asks you to sign in again after a restart.	Sign in again; browser sessions are not retained across a service restart.
Many failed sign-in attempts produce a wait/error message.	Check the credentials and wait for the sign-in lockout period to expire. The application limits sign-in attempts per IP address.
Operation does not change after changing parallelism.	Save the setting and restart the central service.
Old detailed measurements are missing, but long-term histories remain.	Check the retention periods; raw data and hourly trends have different storage durations.

No devices are checked after contract expiry.	Save a selection of at most ten devices under Activation.

A data collector has been paused, and the central server does not check its devices.	For the affected devices, change the data collector to Central server under Configure and select Save all.
