Data did not appear on the second phone

In order:

1. Check that both phones are on the same account — the email address is shown in the profile.
2. On the first phone, open “Sync”. If the waiting count is above zero, the data is still on the device — tap sync.
3. On the second phone, tap sync by hand as well.
4. Check the connection on both.

I would strongly advise against working from two or more devices on one account at the same time. Sync problems can follow if you open the same hive on both and make changes in both places.
