I’ve had lots of discussion with Unity now, including with the development team, about this issue.
Their position is that if I can download things from their web site, there can’t be anything wrong with their Hub code or the Download Assistant, both of which fail in exactly the same way, as described here.
They don’t appreciate the absurdity of this statement, and they insist that there must be something on my setup that interferes with downloads: despite me pointing out that can’t possibly be the case because the downloads would have to complete before anything like that could kick in, I don’t have anything like that on my machine anyway, and if I did, it would affect all downloads not just ones in the Hub and Download Assistant exclusively.
I’ve offered them a solution of putting in some dedicated logging in this scenario: but their developers aren’t experienced enough to understand how to do this, saying that you can’t have logging for when something doesn’t happen.
I’ve volunteered to be a test bed for them to reproduce things, but they said they can’t devote time to fixing a bug for just one person.
I’ve told them to look in these forums and see that it’s not just one person, and they said that everyone else is talking about a different problem that’s been solved to do with the ‘verification failed’ error message.
I’ve said that’s just not the case, and the last message I had from them said that they’d love to solve an actual bug in their code, but they’re not going to spend time on this.
My only solution going forward is to stop developing for Unity, and switch to Unreal.
I’ll lose thousands of pounds of assets and plugins that I’ve bought over the years, that can’t be transferred, and I’ll have to give up working for a while until I can learn Unreal well enough to return.
It’s like John Riccitiello’s legacy of revenge on the Unity community, I swear…
