Hi Community!
We experience something similar to what Amanda described back in August.
One of our salespeople (has an iPhone device) is NOT prompted by the system to log his calls or even create a followup. He has the HubSpot app on his mobile phone, we checked the settings and everything should be according to what HubSpot suggest to make the logging possible.
Everything works just fine with the others so we have no idea if this is because of the iOS system or what, but we need help as this makes his administration process much longer. 
Please help.
