IRCTC Rail Connect app downloaded already in Iphone is not working
I am using the Rail Connect app for my railway booking in India. I updated to IOS version 17.1 one month back and from their my app is not working properly. If I am tries to enter destination using the station initials it is not providing me the list. Same is working fine in my friends mobile as he installed it few days back. I try to delete the app, restarting my iphone but result is same. I also check with the app developer but they said everything is working fine with their side. Please suggest what else I can do? App does not have option to clear the cache. I am also facing the app crashing issue.
Ios Version: 17.1.1
App Name:- IRCTC Rail Connect
App Version:- 3.1.41
iPhone 14 Pro Max
