We have a Xamarin cross-platform app which is distributed worldwide via apple Store. Only the customers from PRC(Mainland China) region are facing flashback issue after installing the app from the Apple Store.Being in India we are unable to replicate the issue even after changing the ITunes region to Mainland China.Any insights into why the flashback issue is geo specific and how we can replicate the issue from India?

Our app is a cross platform xamarin based app. It was working fine earlier but since October, the app started giving flashback issue, but the flashback issue is limited to PRC region (China region). The flashback issue started in the PRC region after iOS 12 update.Is anyone else facing the issue of flashback which is reproducible in only a particular geographic region?We are in a different region, so even after changing the itunes region to PRC and all the other location settings to PRC we are not able to reproduce the flashback error.Any insights?
