Add it all together and it's a major update for the client in terms of fitting in with Instagram on other platforms. Having said that, it's optimised for Windows 10 on the desktop - it works just fine on Lumias (etc) and Windows 10 Mobile, but it's not exactly fast - there are occasional pauses while feeds and images load in daily use. I was testing it on a Lumia 950 XL - it'll be faster on the Elite x3 and IDOL 4 Pro, both of which also have more RAM, but don't expect too much on lesser specced Windows phones.
Winsta UWP has a very active developer and there's an Insider user community here on Telegram. (Access the latter through Unigram Mobile Messenger UWP!) See you there?
As I stated before, Winsta UWP is still highly recommended. There's a lot to like about Winsta, it's a breath of fresh air - you can directly encourage the developer by buying Winsta, since it's a couple of quid in the Microsoft Store. Go on, if you want to see this updated further, buy the developer a cup of coffee in this way...
