While it’s a pretty good vpn all round that’s super easy to set and forget, I’ve been having issues the last ~6 months in Australia with the CIDR ranges getting blocked by Google, Reddit, and the like. It’s annoying to have it run fine for a few days, then suddenly have every second thing I do needing to solve a captcha for it.
Try the freemium tier for a while and see if it works for you - I may be wrong and you’ll run a whole month with nothing, but never hurts to verify.
I think they mean to ask for honest feedback, it’s quite possible your lack of success is linked to the mindset you have. Expecting to fail us one of the most common reasons to fail, but knowing that success requires a lot of failure is a much healthier approach.
Have you you tried therapy to work through some of these issues? It’s helped me quite a lot
