As ever, a few screenshots:
Winsta UWP has a very active developer and there's an Insider user community here on Telegram. (Access the latter through Unigram UWP!) See you there?
As I stated before, Winsta UWP is still highly recommended. There's a lot to like about Winsta's speed and UI, 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...
See also the official Instagram PWA, which works very well (apart from notifications) under Windows 10 Mobile.
