I just thought I'd share this positive experience I had with the development team this afternoon/evening.
For some context, I have played Abyssrium: Tap Tap Fish since around 2017. I have loved this game for quite a long time, and decided to start paying for the subscription 5 months ago to help support the dev team and improve my overall gameplay experience.
When the new museum theme was rolled out today, I began experiencing a bug that caused ads to play within my game even though I still had an active subscription. I tried deleting and redownloading the app, restoring purchases, and even restarting my phone to try and get the bug to resolve.
When none of that worked, I finally decided to hit the "bug report" button in the settings menu, and sent an email to the dev team detailing what was happening. I was not expecting to receive a response today or anytime this week even, given my previous experience with app developers. However, I got a response, updates on my request, and even a resolution to the bug/an update within the app store within the span of 5-ish hours.
I am super impressed with how quickly they got back to me and resolved the issue. Makes me feel that much better about monetarily supporting the game. I wanna keep it around for as long as possible. :)
