ᐅ How should the gap between doors be made?

Do you use the same tape for the joint that is also stuck to the wall? A screed installer on MyHammer told me that this is not done. Apparently, there are people on MyHammer who know what they’re talking about...
Quote from the email:

Please do not use edge strips as expansion joints (in areas like doors, etc.). Otherwise, the screed cannot be guaranteed to be level from room to room, and as you can see, the joints cannot be made straight.

What should I use instead?

Why does there need to be an expansion joint there? Normally, this is not done that way, but it is possible to do it like that.

Why does there need to be an expansion joint there? The expansion joint is essential, and that's why you can also do it that way. It might just end up a bit uneven afterwards.

Why… why wouldn’t there need to be one? How should it be, or how must it be? When is it necessary, and when is it not?

But I still haven’t received an answer on whether nothing should be installed there or if something else needs to be added...
