## What did you see instead?

But the freshly installed Debug versions were adding it just fine...
Looking at Netguard, F-Droid tried to connect to an odd IP `116.203.209.85` that was not matching local DNS queries, so... I remembered the DNS cache setting and after I've disabled it... voila... works now.
/ps: this feature was added under an OTF grant, afaik, feel free to label as needed
