Error code Sparkasse app?

Hello everyone,

Since today I have been getting the following error message when trying to update the transactions in the Sparkasse app.

"The operation could not be completed. (SFCoreMKG.APLError error 0.) An unknown error occurred. Please contact your customer service representative."

Does anyone of you have the same problem? Or do you even have a solution? Is this something more serious? – I'm worried about my money…

System information:

Sparkasse App Version: 6.4.3 (Build 25064)

Device: iPhone 14 Pro

iOS: 17.0.1 (21A340)
