I've been having an issue on MacOS where I can only comment once, and can't comment again until I refresh the app (or quit it and restart). Basically the first comment works fine, then a second comment (doesn't have to be on the same post, or even community) won't work because the text input box disappears.
I'm using it as a saved app in Safari and I'm on a beta version of MacOS (Sonoma, current dev beta) - the saved app feature is new to Sonoma.
Appreciate this isn't going to be the highest priority given I'm on a beta, but Voyager is so nice as a saved app in Sonoma in all other ways I can image lots of people wanting to do it.
The behavior you’re describing is also exactly what happens to me on the iOS17 betas on both iPhone and iPad.
I’ve figured out that if I open up the task manager briefly and then close it (essentially drag up from the bottom of the screen for a very small bit and then let go) the text input box comes back to the foreground and I can respond again. I have no idea how or if this works on macOS.
