Adobe's policy: regular review almost daily?

[hans-g.]

For some time I observe a nearly daily verification of my Adobe CC subscription, is that strictly necessary? In previous times, it only happened sporadically.

Hans-g the check-in behavior you described is normal for an individual membership. If you are offline and have annual Creative Cloud Individual membership, then you have up to 99 days for the check-in process to occur successfully.

For month by month memberships, then you only have up to 30 days to be offline.  A verification check needs to be made to verify that the monthly membership is still valid.

For more information on the check-in process, please see https://helpx.adobe.com/creative-cloud/kb/internet-connection-creative-cloud-apps.html.
