I'm finding that in FileMaker GO after the application first launches and you open a solution. The first time you select an option from a dropdown list or attempt to take a signature it doesn't actually add the data.
Attempting to insert an employee name from a dropdown list. First click doesn't populate. User must scroll through the drop down again and click on the employee.
Capturing a signature. First signature doesn't populate container. User must sign twice.
This appears to only occur if FileMaker GO is opened freshly, as in iPad restart or removing FM GO from running applications. The problem seems to fix itself after the user "fixes" or inserts one field twice.
