People should expect these reddit apps to be buggy when they come out. I loved both apps but I think people have pretty unrealistic expectations for sync and boost. The established lemmy apps have a big head start in getting those bugs worked out.
Can't wait, deleted my Reddit app, and I keep instinctively trying to go back to it when I'm bored (Even though my Account is nuked and the app is gone)
I know work is being done (albeit in a couple places) on getting Infinity to work with Lemmy too. It will definitely be nice to see these Reddit apps be converted to Lemmy apps!
