I’m having a similar issue on FP6 (blocker version 3.1.5). On two builds, including the most recent one of this month.
I regularly have no internet until I open the blocker app. I usually don’t need to toggle it. Tried disabling battery optimisation and clearing cache but problem remains.
Are you still having this issue @d3sox ? Is it a known issue still @rik or was it solved already? Any ideas on how to solve? Bit frustrating in use at the moment.
