Update to forms in Modern Lists, including custom forms with PowerApps - coming soon!

I tested myself and it works for me on my Android Huawei P9 Lite using Chrome web browser? When I'm in the list and select New/View/Edit I can see PowerApps form. I don't know where do you want to use from customization?

But I have noticed that hamburger navigation is not working correctly. When I navigate to one of my lists it works OK but then after when I press Hamburger navigation it shows the navigation for a glimps and hides immediately.

And if that is not all...Yesterday I noticed that if I have multiple lists with PowerApps Form enabled it shows only the first Form I opened. So if I navigate to "List1" and open one of the items it displayes OK. Then If i navigate to another list (let say "List2") and try to open PowerApp Form it displayes the previous Form (from List1).

I posted this yesterday on PowerApps forums https://powerusers.microsoft.com/t5/General-Discussion/SharePoint-list-form-not-showing-correct-PowerApps-form/m-p/237997
