However this is not my original question. If you don’t want to answer it fine, you can simply say so.
I write this with the best intentions, after 30 years on the web and being a dev myself in another field I would know how to ask for help.
Interesting reply. Obviously the developers of Blokada are interested in fixing the bug/issue in the current version so you are able to upgrade and also everybody else profits of the fix. How will the old version help you to fix the problem in the long term? If you provide enough information about the current situation chances are high that there might be a quick fix.
But yes the old version is a short term solution and would help in the meantime. Maybe they will provide it if contact them per mail as requested.
