RichLinkPreview is not shwing on relaese build

[leonidas79]

RichLinkPreview is working and showing preview in debug build in emulator and real device , but once i build a release build it's not showing preview with no error in logcat.
is there something that i should add in proguard ?

i tried this but still not working :
