I know that the windows version is not the product.
I am very happy I have bought the mobile version, only to discover the windows version as a nice plus.
I am so happy I tried the new prerelease 2.1 both on mobile and on Windows.
No problems on the mobile version (so far), but the new Windows version shows some pops and clicks during sound play.
I want to tell this only in case this may show a possible bug on the mobile version too ("The product").
Hope this helps.
Thank you to all.
