Room cards are not always loaded

Hey guys,

unfortunately I have a problem with my new dashboard.
After getting more and more complex, the room cards don’t load every time I open the dashboard on my smartphone (iPhone). About 50% of the time the room cards load as they should, 40% of the time they don’t load at all and 10% of the time interestingly only some room cards load (I think these are the room cards “Flur” and “Küche” in such a case, but I’m not sure).

I think this has something to do with the fact that the cards dynamically scale in height when the dashboard is opened, but I’m not sure about that either.

Here you have the yaml code to the room cards, the rest of the dashboard works: Room Cards - Pastebin.com

I am very happy about your help!
Best regards

PS: interestingly, the problem only exists on the smartphone. There are no problems on the PC or Macbook (Firefox browser).
