Contacts app unusable on IOS

I have loaded my contacts and have no trouble accessing them on my Mac using Firefox. However on iPad, if I touch the Contacts app icon, I can only see the first contact. Also, if I touch the search icon, a Text box appears but it disappears as soon as my finger is lifted.

I am able to search contacts using the Contacts icon on the right side of the window (Next to the Login circle).

It works fine for me, but check on github issues.

Here is the setup guide I used.
