Lege Klantkaart/Empty CostumerCard
Whenever a user raises the issue that the costumercard remains empty the following guide can be used to resolve the issue:
First find the Algemeen_MedewerkerID located in the security database in the algemeen_medewerker Table and copy it
From here search for
Algemeen_InstellingID =75 and Algemeen_MedewerkerID =(xxxxxxx)
at column waarde you'll have corrupted json, just copy waarde from some user that got no issues and insert there and then you could ask client to update klant dashboard cards again
