Upgraded to a new phone. Lost 4 days worth of Activity data in the process. Weird. Random. Frustrating. Not the end of the world though.

@vincent It will probably come back, it just takes a while to sync up sometimes.

@rosemaryorchard OK 👍 Hope it does. It was even from a fresh backup, so not sure what has gone wrong.

@vincent Imazing 2 does a good job of making full backups on a Mac or PC.

@vincent I agree that it's very weird! But at least it comes back :)
