Relative Layouts with text-areas crash on Fenix 5x

Hi, I use relative layouts with text-areas in my watch face. When the user runs the watch face in preview it works fine, but when the user selects the watch face, it crashes and the watch reverts to the previous/default watch face. The crash log file has this:

It crashes on line 190 in the onUpdate function in my view class. Line 190 has this:

View.onUpdate(dc);

The description in the crash log has: Details: "Could not find symbol '<Toybox_WatchUi_TextArea_>>fitTextToArea>'"

The target is Fenix 5x.
