Did that with lemmy, but at least in my case it just happens too often that I get an infinite loading circle when switching threads and then I have to reload the entire page, which isn't possible when not in the real browser. Even closing the web app and reopening them doesn't help but once I open the page in Safari it works just fine.
Mlem for iOS just got an update which gives us the compact thread style I much prefer over the current web app look but it seems like I can't edit comments there and I also don't see any notifications so there's still a lot of work to be done before it becomes an option.
And kbin I just don't use on the phone at all as long as we can't collapse comment chains.
