VW EU Data Act setup, but SoC not update

[ambitzgi]

Describe the bug

I have set up the the VW EU data act (every 15 minutes). However, it seems that the SoC is only updated very rarely, maybe once a day. Today, the whole day there was about difference of 7 to 9 % in the SoC between EVCC and VW-App. The delta was most probably because my Buzz was charged in the morning for about 45 min as Gastfahrzeug.
However it never got updated during the day. Now after the PV loading the difference is even larger: EVCC 63%, in real / VW app 79%.

Most probably I did configure the VW-EU-Data-Act not 100% correct. However I don't know what I did wrong.
Second problem, I don't find a possiblity to download my data as zip file on the VW-EU-Data-Act web site.

Steps to reproduce
