Android - Scroll text size fixed or adjustable?

Hi
Please could you confirm how to change the size of the text in the ‘auto-scroll’ window? It looks like the size is fixed?
I have tried changing the App font size, and phone system text size but those only seem to impact the ‘Lesson’ text size.
I have found that with more advanced lessons where sentences generally get longer and more detailed, this can actually push the current text sentence way past/above the top of the phone screen as it tries to show both the current text plus always the following/next sentence on auto scroll with timestamps!
Minor issue I suppose in early sw stages, but thanks any how for any further feedback or advice on how to adjust text size.

Hi
Sorry, I did eventually manage to change the scroll text size after all by changing the samsung phone system fonts to the ‘lowest’ size to avoid the clipping of text, but that made the fonts for the rest of the phone apps etc also use the smallest size for other apps, making some of them almost unreadable (for me anyway).
Is there a way to link the scroll text size to adjust along with the lesson text size maybe … ???
Apologies if I’m missing some step or function here, but feedback appreciated.
Thanks again, br, Frank
