Problem with electric parking brake/fixed parking brake after recall action

Hello dear community, my Q2 was affected by the callback action of the electronic parking brake. Now, after I have my Q2 from the Audi dealer again, I notice the following negatively: In the case of an electric parking brake, I have a 50/50 chance, whether the Q2 releases the parking brake directly independently when driving, or whether it simply stays inside and you drive against an attached parking brake. “Update” of the electronic parking brake at the Audi dealer I never had this problem. Is that normal? Do I have to solve the parking brake manually somewhere? Do you have similar experiences with the electronic parking brake? Many greetings, keytronic
