Snapchat doesn't work on Mobile Data

[W Martin]

Recently I have rooted my phone (galaxy s5 mini) and installed a custom ROM on it (slim6), ever since, snapchat has not been working on mobile data. I am not able to open any snaps nor recieve or send anything. I have tried clearing the app's cache and data but it didn't work... Snapchat works perfectly fine on WiFi. Apps like whatsap any my browser do however work on mobile data.

Some help would be great

Thanks
