Windows 10: Purchased MS store app no longer shows as purchased

Hey all, having an interesting issue where the app I purchased in MS store is no longer showing as purchased. This is making it so I can not re-download this app. I'd rather not purchase something I already have. I'm logged into the correct account.

MS App Store Purchases

I bought an app in MS Store with my desktop, hoping to be used on my Windows Phone. The purchased app shows up on my desktop, but I cannot migrate it to my Windows phone. I have no use for that app on my desktop. Is it possible to migrate the purchased
app to a Windows phone?

 

Online activation and purchase of Windows 10 using PPPOE and MS Store

I have installed a Windows 10 Home using media creation tool from Microsoft. Now I would like to activate it and purchase the valid key. So, I step into Parameters > Activation and select there a Go to Microsoft Store entry. The window with MS store page opens, but when I click on Buy option I get an error code 0x800713AB with a description "Internet Connection required".





Obviously, I am connected to Internet.
But I am using a PPPOE connection which is rather good and MS store page can be opened in browser (although price there is different (higher), heh).

If this may be helpful, after boot I am connecting ("dialing") to my connection manually, this is fine for me. Another interesting feature: in Control Panel > Network and Internet I have a "no Internet Access" notice, but everything works fine. I was also able to install some application from MS Store, although got the same error message, but it installed and worked.

So, how do I get past the 0x800713AB error message and purchase the activation key with usage desktop version of Microsoft Store?

Please help suggest why this is happening, and how to rectify? Apps are downloading and updating absolutely fine. There is also no Issue with my account.
