Difficulty accessing multiple email accounts

Difficulty accessing multiple email accounts

I have 23 email accounts all accessed in the one Zoho account and have been using this system for about 10 years.

Five or Six of the email accounts are shown on the bottom left hand corner of my screen (at the bottom of the column where in folders - InBox, Trash etc are).  There is a vertical slider I use to scroll down to see the other email accounts and when I click on one then that email account appears on the screen.  __ SEE ATTACHED ___

Earlier this week the slider disappeared. I have rebooted the PC (Windows 10) and tried accessing Zoho Mail in various browsers but the slider is gone which means I can only access the 5 email accounts listed.

What has happened ?
