1. Map issues

The map saved in my app is suddenly misaligned, resulting in the robot unable clean the zone/room/area properly. It even went to the wrong area.

The charging station is also at the wrong location in the map. The location is off by about 1-2 metres. The charging station is in my living room but the map shows that is it in my bedroom.

There are no carpets in my house, except that it is always stuck in my kitchen that i have to manually remove it when it is done as the floor is not on level.

I run the robot about once every 2-3 weeks.

How do I revert to the old map? I am unable to do it on the app. I only have one map saved.

Can the technical team please advise how to solve this issue?

2. Hardware update - My RV30 version is V1. Can it be updated? 

Thank you
