I'm (almost) beaten by this: I can find no way on my Kobo Clara to adjust the fonts and text sizes.

User Guide Page 39/40 details how to do this:
Changing text and font options on your Kobo eReader
Your eReader offers several different sizes of text for most books. You can adjust the text size, fonts, line spacing, and justification to make reading easier on your eyes.

However, on "tapping middle of screen" the Reading Menu does NOT have an Aa Text Icon.

I've checked the firmware is up to date and - being new to this ereader - and navigated every conceivable setup menu I can find, I'm now stumped. I've also tried this with various epubs/pdfs etc and the

How do I enable/find this option - is there some setting somewhere that disables it? Or do I have a faulty Kobo?

thanks
