I mean it's practically annoying to see a recap episode, when you literally waited for the next episode, of new content, to appear as you waited for it. And it may seem possible as well, that the reason for this anime to do such a thing may be due to some conflicts that some viewer may have with understanding what's going on in the story, to the point that we're at right now. Or they're just lacking the budget or time to actual animate and finish everything accordingly.
But I mean why are we even complaining? We watch their shit for free. And they're not profiting from our money. Aside from that, the anime is actually pretty simple to understand, the difficult part that some people might have a tough time understanding would be some language used, like German food, wurst (the sausage). Or just some military like strategy and logic involved in the show, if you are unfamiliar with civilization like games or study history passionately, then it's going to be kinda tough to understand those part without reading it carefully. Aside from that, this shit was unnecessary.
