Sorry, where? What? I don’t recall such a thing in v5.
If there was an android incompatibility the app just wouldn’t install.
The blokada version on the Google play store is also able to manage your plus account.
It does have VPN implementation.
Regarding features:
We have asked what you’d like to say next here. Unluckily there was rather limited activity although this seems to be such a pressing issue for lots of folks in the community including myself.
Feedback is key for community centered development.
Engage in our polls and see what happens. That’ll make a measurable difference compared to leaning back and hoping for the best. This was why I engaged with the project in the first place 
More features will arrive but underlying data of polls will definitely increase the precision of updates like they did back in the early days.
The simplest solution possible to most cloud and plus users is to use the play store version of blokada.
That’s the main player by now hence has been renamed to Blokada while the website version is called Blokada libre
