This is a shame, I'm sorry to hear.

I loved this app for a long time because it was the only one (that I found) that would cache comment threads on the device - this meant I could read comments on the subway and/or without access to the internet.

A few months ago the app was rewritten in Swift and lost my most treasured feature, not that it matters anymore.

Thanks for the years of connectivity-anxiety free comment reading!

Edit: If you do get passed this (I really hope you do) please consider adding an option that would fetch and save comments on the device. I'll pay for it.
