stay on v4 - use AdGuard DNS as long as it works, otherwise change to your ISP for that time.
update to v5 - use AdGuard DNS while it works, if it doesn’t use another DNS which is DoH but doesn’t block content.
In both cases Tasker (or a similar app for example Automate) could come in handy: they can turn off Blokada as soon as you are on cellular data. A guide on how that works can be found here:
Tasker is an app. Automate is the open-source version of it downloadable on F-Droid. I think Tasker has to be paid.
Edit: I’ll check whether I find the link, one sec:)
Perfect:D Then I hope you will be able to work with that app in a good way, be sure to post a new topic if you need help with that:)
Any more questions for now:)?
