Thank you Tom.
Yes, I tried using different fonts of Tibetan and it’s working in many features except with one issue. I changed my device language and helped me to display date time but it doesn’t show with proper font size. Can you help me this...
And I wish to show my apps in Dzongkha font by simply changing my device language which doesn’t support right now. Is there any that I can contact the Apple developer or localization team ??
