Multiple chats going direct to missed

Multiple chats going direct to missed

Hello Zoho Community.

In the lasy 3 or 4 months I've been trying to solve something that it seems to be impossible.

A lot of chats that my end-users opens are going directly to missed or popping into as notifications and suddenly disappearing even if my operators are online. 

I sincerely do not know what else I could do to solve it. I've tried SalesIQ app and its very glitched, tried enabling all popups / notifications on my browser and yet this keeps occuring.

Did someone else faced something like this? What is the solution for it? Everytime I open a new chat with Zoho support team they tell me that its my browser config or my agents that do not act correctly.

Please, someone help me on this,

Regards,
Rodrigo
