HI @ali4fun,
I checked your case, however, the given information is not enough to investigate further the problem.
Can you provide more info about the problem and your environment(the exact versions of tns-core-modules, tns-ios, tns-android, used nativesript-ui components)? Also, it will help if you send us a sample project, where the issue can be recreated.
