I use a 10 inch Android Tablet that I have learned works a bit differently from practically all other Tablets (Mike told me that when he had to buy a copy to fix one bug I had) - so never know what is just on my machine.
On my Tablet, for a long time Add Family would freeze after a short time, then re-size screen, then re-size again. If I got relationship chosen, first name entered, and living status and gender chosen before the first freeze, then I could click save after a re-size and it would save, then I could edit normally.
Then, much to my pleasant surprise, it became possible to do Add Family normally, no freezing.
Then for a while there, Add Family was working fine on my Tablet. Now it is back to being problematic - freezing at times tho not exactly in the same pattern as before - do not know if Geni changed something again, or if it was because I finally did the update chrome I had been being told to do for a very long time.
