Pro+/Pro Version

I want to use Learn Quran Tajwid Pro+/Pro version on multiple devices!

If I purchased Learn Quran Tajwid Pro+/Pro version in one platform, can I use it on other platform?

Mine was Pro+ but it comes back to the basic version!?

I cannot use the available payment methods, but I really want to purchase the Pro+ version!

How can I purchase the Pro+ version?

What is the difference between the Pro+, Pro, and the basic version?

I think we should not make money from apps such as Learn Quran Tajwid!
