Text on Mobile, either too small or too big.

Hi there,
We’re having an issue with the responsiveness of text layers, we have set up the layer styles as we require the text to appear on desktop screens, but when choosing between “Resizable Layer” on or off, the result on mobile is that the text is either too big (first 2 slides, as off) or too small (3rd and 4th slides, as on).
Could you please assist us on how we can have an appropriate text size for the mobile version of our slide?
Thanks a bunch!
