Still not working correctly in version V17.3.0.17 (iOS only). Everything is fine on Android.

Hi Tomas, 
 
We regret for your inconvenience. 
 
Due to some technical hurdle, we were unable to move this fix into our latest weekly nuget release (17.3.0.17).   
 
Surely will resolve the error and move this fix into our upcoming weekly nuget release which is scheduled to be rolled out on October 22,2019. 
 
Regards, 
Hemalatha M.
