'Could not refresh. Please try again.' (ver. 2.7)

I have sideloaded ver 2.7 using Extensify. 

Upon opening Snapchat after installation I received the _'Could not refresh. Please try again.'_ message however the Stories feed seemed to refresh and function as normal. A short while later the Stories feed stopped refreshing altogether. 

Deleting the cache and reinstalling Snapchat doesn't appear to resolve the issue.
