Slow and deleted contacts

I mistakenly downloaded this app which took a very long time to synch my iPhone contacts with my Google contacts. It deleted any contacts from my iPhone that weren’t in Google and it doubled all the contacts in Google. Fortunately I had a backup of my iPhone contacts and Google allowed me to merge the duplicates. It’s painfully slow.

The new rewritten version no longer works

I bought the Pro version a long time ago. This new version no longer works at all - click on the Google button to sync and nothing happens! Also the new app refused to recognise that I had paid for it, and just filled the screen with ads. I had to delete the app and reinstall for it to recognise my purchase. I would give it zero stars but can’t.

$120專業版，要簡單備份聯絡人功能還要再要求$90購買才能用，

不知道花了$120專業版的意義爲何？還是會跳廣告干擾，而且簡單的備份聯絡人功能，還要再要求$90購買才能用，一條牛扒好幾層皮，$120專業版費用白花了
