Theres a lot of weird setup often required on the backend in my experience, but when it works, it works well. But until you get everything dialed in it can have weird issues that don't have a clear path to fix them.

It might be better in their weird AIO solution? But i dont like the idea of giving a docker container the ability to spawn more containers. I just use one of their normal docker containers and have had to manually change a lot to make it work as they actually suggest. Like just recently i setup their notify_push plugin as it improves performance - but the provided setup instructions didn't work in my setup and i had to manually tweak several things.
