I have received this error on Grapevine twice. Look at the bottom of the provided screenshot.

@yuyutsu thanks for highlighting, would request you to check app version from settings page. Ideally this shouldn’t happen if you’re on 2.0.15

Yes I am using v2.0.15 on Android 12 (Moto Edge 20 Fusion). I am only able to open the comment section when I am on the home tab (so I have to scroll till I find those specific posts through recent sorts). I was not even able to open this post comment section to reply to you from the notification and software 'group'. I posted to help you all.
