@JonathanMosen Hi Jonathon, I just listened to your Mona related podcast yesterday! Very informative, thank you. I'm glad Mona is providing much needed accessibility features and hope it inspires other apps to do so as well.
Mona does include the words "Followers Only", but easy to overlook. Better than other apps for sure, where it
appears as a tiny lock icon near the top of the post with no text, which is difficult to understand meaning and often ignored with all the other visual clutter.
