Here is a current poll.
“11% of Britons say Brexit has been a success, with more Leavers saying it has gone badly than well”

> And so far, do you think that Brexit has been more of a success or more of a failure? %
With 62% saying failure (the rest are don't know/neither).
Note that only 55% say it was wrong to leave, and on such a close referendum anyway I'm not even sure that's a statistically significant different answer than in 2016.
Key point: you can think it hasn't gone well (managed poorly, opportunities no taken, whatever) without thinking it was wrong, or even that in hindsight being in the EU is better.
(You can also have voted to remain, but now want to make the best of it, and think it's going well/badly - it's completely independent.)
Conveniently ignoring that only 30% say we were right to leave. Nice try.
I was comparing the 'failure' to 'wrong' figures; yes you can also compare 'right' if you want. You can also compare many other figures that I don't think you are 'conveniently ignoring', it's just if you want everything you can go and read the linked survey results.
I think that's why so many US voters are now telling each other "I hope you get what you voted for" after the last presidential election. Sometimes you need a really, really bad hangover to decide that you need to make some changes in your life.
