Insert link on picture in signature not working

Insert link on picture in signature not working

Hi,

I have tried adding a link to a picture in my signature, however I always get the "Selected text" field popping up, instead of just the web address (reference : https://www.zoho.com/mail/help/insert-images.html#alink3)

I tried from Chrome and Edge, and I have the same behavior.  I have made sure that I have selected the image before clicking insert link, to no avail.

I have attached a screenshot showing the sequence of actions that leads to the problem.

Thank you for your help.

Stephane
