Hi Josh,
Thank you for your patience.
We have checked the reported issue “Application crashed when IsScrollingEnabled is set to false, with nested listview in Android version < 6.1” and we unable to replicate the issue from our end. We have prepared based on your scenario and checked, it is working fine as expected from our end. We have attached the sample for your reference,
We have tested with Syncfusion update version 17.3.0.28 and Xamarin.Forms version 4.3.0.991211 in the Moto E (Android version 4.4.4 - API 19).
Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us back with the Device configuration details and ListView related code files. It will be helpful for us to check on it and provide you the solution at the earliest.
Regards
Gokul Saravanan
