Swear I’d never had any problems with Internet connection. The statistics work fine, but there's a problem with the achievement awards. In the Internet they say that this problem usually disappears somehow with the New Year (don’t ask why, I found it in the nets), but in my case it didn't work. In June 2020, my achievements stopped being recorded at all. I have been playing desktop version (Windows 10) of Microsoft Solitaire Collection since December 2019.
Please be patient since English is my second language.
