Yep 👍 Sorry, I wasn't entirely clear about this when writing the problem also happens in a simulator and on device. I do inject the environmentObject properly in the app. Also, MiddleView (which contains the environment object) opens fine, just when you try to push InnerView, it gets stuck in an update cycle.

Once I got it working properly, I will write down what I've come up with and what I've implemented and publish it somewhere. Maybe it will help someone :)

Update: I've come up with a possible solution using such a "buffer" database for incoming changes. Some first, simple tests are promising. I was able to add/modify/delete data on one device and it synced to another device, keeping all relationships and such in tact, even though the order of fetched batches are not always "correct". I might still hit a road block with this, but maybe I'm getting somewhere.
