I see a number of complaints, similar to mine, about font size going to tiny on its own - but nary a fix from Yahoo.

We need to know how to fix this - the directions indicate to open settings and we'll find the fix there - that is not the case.
Some of us have visual impairments (as do I), some people just like larger font size for ease in reading - the tiny size is almost non-ADA compliant.

Would REALLY like a solution. Help? I may simply switch to Proton mail as my mainstay. They give answers.
