You haven't failed. You've been fixing the wrong problem.
Vet guidelines don't treat "weeing outside the tray" as one problem: the first thing they work out is whether it's a puddle or a spray, because the fixes are completely different.

Why "I've tried everything" so often made no difference
You've mopped, scrubbed and washed the duvet again. You've moved the tray, changed the litter, bought the spray and plugged in the diffuser. The vet said "it's behavioural" and sent you home. And you're still finding wee, still smelling it when you walk in, still wondering if anyone at home has started saying the word "rehome".
Here's what most advice leaves out.
A puddle and a spray are two different problems
A puddle is your cat going to the toilet in the wrong place. A spray is your cat leaving a message. More trays and new litter can help a puddle and do nothing for a spray. That's why one thing "worked for everyone online" and not for you.
There are 5 possible causes, and each product covers one
International vet guidelines group house-soiling into a handful of causes: the body, the tray itself, stress and tension between cats, territory, and a spot that has become the toilet. A spray, a diffuser or a new litter covers one of them at most. If your cat's reason is a different one, it can't help, however much you spend.
Your cat isn't doing it to spite you
The same vet guidelines are clear: house-soiling isn't about spite or anger at you. It's a cat telling you one of its needs isn't being met. Once you know which one, you know what to change, and punishment (which only adds stress) is never part of it.
Find the cause first. Then fix that cause, one small step a day.
The same order vets and behaviour researchers use, turned into something you can do at home tonight.
Check (about 3 minutes)
14 questions about what you've seen: where, how much, which surface, what's changed at home. Because research shows no single sign tells a puddle from a spray, the check combines your answers into your cat's most likely type and cause. Anything that needs a vet comes up first, in red.
Start tonight
Your result gives you 3 things to do before bed, so the next 24 hours already start differently. Then your 21-day plan: one small step a day, about 5–10 minutes, each with a short "why this works".
Track, then stay or switch
Note each accident in the tracker (it takes seconds). At day 7 and day 14 it tells you whether you're on the right plan or should move to the next most likely cause. No more guessing, no more buying the next thing on the shelf.

Your questions
I've tried everything already. Why would this be different?
My vet said "it's behavioural". Is this for me?
I live in a small flat. I can't have a tray in every room.
The plug-in diffuser didn't work for us. Do you use those?
Is this a diagnosis? Does it replace my vet?
We have more than one cat. Does it still work?
How long will it take?
Is it a subscription? What do I get, exactly?
What if it isn't right for us?
Tonight can be the last night you're guessing.
Find your cat's most likely cause in 3 minutes, do the first 3 actions before bed, and follow one small step a day from there.
