OK, this is my last effort to use ZOHO. I have registered a new email that I wish to use with a free ZOHO account. After about 100 or so OTPs arriving - all timed out because of their 15 limitation, I have to call it a day.

Support is next to useless. They seem unable, or unwilling, to just verify my email and let me get on with using Books. 

Just sending me emails and then doing nothing is a waste of my time.

Enough is enough.
