I have the DJI Virtual Flight app installed on both my iPhone and iPad. However, even though I log in to the same account, they don't seem to have their data synced (e.g., the time trial results/stars, unlocked map, etc.).

Is it possible for me to sync the data?

Especially because of the following issue: https://forum.dji.com/thread-287666-1-1.html
I usually used my phone to do the time trials, but now it doesn't work...
