Robovac L70 Mapping

Hoping someone can help with the eufy L70 vacuum. I ran the vacuum through the main living areas and created a map that I was really happy with. The next time it went to clean, the map cleared and it appeared that it was going to start mapping again from scratch.

I can see my preferred map in the cleaning history on the app. Is there a way to bring that map back? I wanted to do some zone cleaning from that map and make it my default map.

I’ve the exact same issue.
Very poor user experience. I’ve had to map the apartment, twice. One press of a button and thr map vanishes. No warning no way to get it back.
