I am on the process of testing the CRM functions,

I am using both the web platform, and the app.

And in the APP came across a problem in the calls registry:

The app automaticly recognises the calls my phone makes\recieves and , in the outbound call gives me the screen with the info, so I can finish the registry.
But, if I recieve a call from that same contact, after the call, on the finish screen, it gives an error when saving the registry. (see print screen: I use portuguese language but it says:" Something whent wrong"?

I can add an outbound call manualy, but, in the "automatic" process, it gives that error.

It happens in multiple contacts, some added manualy, other added from my phone phonebook.

All help is welcome, thanks in advance.
