In FM Go 15, all may not be well. If you have lots of layouts, check them in FM Go 15. For my solution, created pre FM Adv 15, text in some text fields in some layouts display incorrectly in FM Go 15, and correctly in FM Go 14. In this case, text formatted to display vertically centered in text fields, does not show vertically centered in the text field in FM Go 15, but displays correctly in FM Go 14, and in FM Adv 15.
Have not yet figured out what maybe causing this issue. Probably will have to delete the fields and recreate.
