Yes – when you open Mabui 77 for the first time on a second device you will need to go through the studio migration screen as before. The process is the same but this time you may be prompted to download the migrated studio that was uploaded from your first device to the Mabui platform.
To ensure that your studio continues to be synchronised correctly on multiple devices you must ensure that each device is updated to Mabui 77 as soon as possible. If you only upgrade one device then the two devices will be checking against different backup copies of your studio and they will no longer be synchronised correctly.
