Hi AW2307, thanks for flagging this. We’ll look into Markdown performance, though we don’t have a workaround or a timeline to share just yet. Sorry for the inconvenience.
I think a short-term solution could be to only render markdown for the current viewport and a buffer around it, rather than loading everything at once on opening a map.
Even better, though maybe more complex: The processing would handle all cards at once but in a background thread, without blocking general interaction with the map. Currently, it freezes the map completely.
On a macbook, the system handles it with raw processing power, here it’s not reproducible for me. So please test on an iPhone to reproduce the behavior.
