Hi,
I’m sorry to hear that.
auto sync function between phones does not work with locally stored data 
If you switched to a new phone, does it mean you still have the old one?
If so, you can migrate them.
here is how you can do that:

does this work?
In addition, I can only tell you that the next version will have an automatic sync feature. The next version is already in the beta testing stage.
