I use RadNumericBox in my UWP app, but I have a problem with decimal separator on my mobile device. I can't enter the separator when keyboard input method is ukrainian, russian or others with decimal separator ",". I tried change culture to en-us (by default is uk-ua), but I still can't enter a separator (either "." or ",").
When I change keyboard input method to english, all work fine with different cultures. On my desktop everything always works perfectly.
How can I solve the problem on my mobile device?
