@janbolat Thank you for reporting this issue. This is a known ANR issue that some users may experience during the initialization. This has been fixed in the beta release. Please give it a try and let us know if the issue persists.

hi @janbolat please try the latest version of Android SDK, it should have most of these issues addressed.
