If you disable both the left and right swipe, it will automatically enable full swipe to go back.
Right now I’m having some technical limitations with React Native, where it’s not possible to have full swipe to go back without disabling both swipe gestures. It’s on my list to look further into, but I’m not expecting to solve this in the near future.
As an alternative to the long press, menu icon, and swipe actions (when disabled, follow up to this and your comment about not expecting to solve it soon) in comments and posts, would it be possible to add an action to the upvote and downvote count, where when they’re touched they will add/remove the respective vote?
