Hi @AnandkumarBShetty
Can you send us the project or sample one, where the issue can be reproduced?

[AnandkumarBShetty]

Hi Nikolay Tsonev, I have my Web application which is under Development however it is good to go with NativeScript with already built usecases. The best way to see the issue is through the skype call. I have posted 2 other issues: #2008 #2009 Even these can be looked at it. If you need to look at the code, we can go for Skype call which can help to nail down the issue. Thanks, Anand
