Back in October of 2017 I purchased Airmail on the Apple AppStore for $4.99. It came with a certain feature-set that I wanted so I forked over the cash.
This week they decided to cripple the software and make essential features, like notifications that you fucking have gotten a new email, hidden behind a subscription wall. This is an app I paid for that had these features.
It would have been a different story if they had some new feature that had the subscription wall… but no, they killed the app I paid for.
I just wish I could get a refund for the purchase since the thing I bought is no longer that thing.
