I am happy to,say that the two issues I had after purchasing the full version of ToddlerLearningGameEduKitty have been resolved. After my purchase, I was unable to 'share' ToddlerLearningGameEduKitty to my husband's iPad. I tried several times, multiple ways to no avail. I finally gave up and contacted the developer(s). I then read the reviews and saw that others had the same problem as well as one with the sound. I checked sure enough, I, too, had no sound with the paid version. One the developer responded, I went to the FAQ page and followed the directions for restoring ToddlerLearningGameEduKitty . Although I had previously tried this step, I guess the umpteenth time was the charm because I now had the full version of ToddlerLearningGameEduKitty on both iPads. I also saw under the FAQ list, how to correct the sound problem--make sure the slide switch is not set to mute. As I have never had an issues with any other apps, I never even thought to check this, but once I did, I had sound. I guess there are some differences in how ToddlerLearningGameEduKitty works in the freemium vs. premium versions. I am just glad that everything is working as my nearly 18 month old granddaughter really loves ToddlerLearningGameEduKitty . It is a great tool for introducing and reinforcing concepts like counting, colors, sizes, sounds, shapes, and more. I am very glad we purchased the full version and definitely recommend it.
