I have a global field on a layout that no matter what automatically clear the first letter/number typed into it on iOS only (not on Mac).
There are no script triggers or permission issues. The user could type for example "cat" and the letter 'c' will appear for a brief moment then delete itself leaving the global field only populated with "at".
Subsequently, the user can delete the contents of the field and re-type "cat" and it will work just fine.
It doesn't seem to matter what is typed in the field, always the first character is deleted automagically and the rest is not.
Again only on FM GO and with all privilege sets including Full Access.
FM Go 188.8.131.523 on iOS11.2.2 (where the issue occurs)
FMPA 16.0.3 on MacOS 10.13.2 (No issue)
FMPA 16.0.3 on Windows 2012r2 (No issue)
