Ok something weird happened yesterday. I am using a rosemary font on my Samsung and now the google text app doesn't apply the font anymore. Every other app, settings, I mean everything has the rosemary font except the messaging app.
I have done the following
-force close the app
-ensure font style and size is correct
-tried other apps (none affected)
-tried the pinching method to make the font bigger/smaller.
-the native samsung text messaging app has the rosemary font applied.
