Firmware v0.3.4 b257 has a fix for the OpenWRT package repo URL and is now available!
The opkg feeds now point to the OpenWRT 18.06.1 package repos. Keep in mind that you'll still need to follow the procedure from our documentation to enable the OpenWRT feeds
@akhileshthorat please try it out and let me know how it goes. I believe it will fix both of the issues you identified.
After uncommenting the OpenWRT package repos in /etc/opkg/distfeeds.conf, opkg update works as expected

And installing packages from the OpenWRT repos works as well (the adblock package is not the the Onion package repo)
