Ems trackr

I downloaded the free EMS Trackr App.

It work very well BUT after a while the app suggest to buy the Pro version which I am interesting in.

When I click on the Upgrade now button It seems that I am not redirected to the App Store.

When I click on the Purchase button the App ask my Apple password.

Of course I don't want to give my password to this company.

How can I be sure that I am on the App store?

Where can I contact Apple about this?

You can try with the following tracking number: EJ554815855TH

Launch the app, enter the tracking #, quit the app and relaunched it.

Refresh the tracking and you should have the upgrade message.
