just looked it up and couldn’t find a decent client for ios. There was Monal but it looks more like a draft rather than a finished application. Things don’t even have padding or margins. The snikket one I won’t even mention, you can’t expect people to use something that gives them visual discomfort.
manjaro was terrible when I used it (several years ago), imo it is fundamentally broken. I would suggest trying a smoother arch install. I always recommend endeavoros because I had an effortless experience with it.
