Cannot update iOS apps using 1.1.1.1

Zero Trust 1.1.1.1

Hi all.

Since updating iOS devices to 13.2.3 and 13.2.3 I wasn’t able to update app or install new ones.
After two days of troubleshooting with Apple support and my ISP, I was advised by my ISP to remove 1.1.1.1 from my router config.
I was able to update apps via mobile data.

So clearly it was something with my wifi.
After removing this dns, I’m able to update everything.
Placing this dns again and I’m not able to install new apps or update apps.

Did anyone encounter this?

I’ll have to check more closely, but when I use my own Outline VPN, I have the same problem.
