Working pretty great on my 12.9! Some community plugins aren’t compatible with mobile, but I can live with that.
Sliding panes, you can’t scroll left and right with trackpad… but that’s a minor nuisance. I’m very happy with it.
I would caution against getting rid of laptop. The iPad File Manager is absolutely woeful and you will not be able to modify your obsidian configuration because it is stored in a hidden folder, (.obsidian), which you can’t see on the iPad, no matter what you do. I have a 3rd Gen iPad Pro and am majorly frustrated by the file handling facilities - so much so I use my iPad to log in to my Mac desktop to use obsidian.

Pete

I had this problem after about a year or two into using Discord and spent a good weekend learning the best “strategy” that I’d be happy to show you. It won’t take you a full weekend to pick up, just 10 - 15 minutes.
