Move from Legacy App to 3.0

Look on your iPhone and see if you have two icons now.  A blue icon of the older app and the purple moon that you just downloaded.  If you have both, and only if you have both,  delete the purple moon crescent 3.0 app.

Then go to the App Store, search for TimePassages Pro APP, which is a blue icon and now called the Legacy App. 

Select update, this will bring you back into your older app, where all of your charts live and then you can start the onboarding/migration process.  You will create a login with an email and password of your choice with a free   year subscription.

Please let me know if this helps.
