Try this way, you can install in official methods without third party app. It is worked for me. First power off your phone and then remove all sim card and restart your phone and turn off location and then clear all data and cache of the galaxy store application and connect to US server(vpn) and open galaxy store application(allow all permissions it asked) then open settings > display>fonts > download fonts (it will takes into galaxy store software fonts section) in fonts section click top free then you will see the rosemary font for free and download it then insert sim card and power on your device.
