We recently activated the Credit Notice notification and see it being triggered incorrectly.
The same can also be observed on the company details/information page.
It seems it triggers as soon as the amount of credits goes bellow the count of devices but then picks the first date a device service would expire as last coverage date even though there would be credits left after that activation.
For our setup this is really irritating and counter productive, as it shows tomorrow (30.07) as last coverage date, while we will have credits until roughly end of august.
