We have just noticed that there is no more option to record the description for the call.

No such an option any more in the Create Call dialog however the field exists and available.

I asked the support via chat and received a response that this has been a normal behavior now since the last 2 days.

And, to record the description, we have to firstly create a Call, then go and edit description in it.

WHAT?

Is that serious? Have you ever tried to call clients and register call using Zoho CRM?

It was quite difficult to register a call or event in this small dialogue with several pages. 

Now it is a complete disaster.

Please fix it back ASAP.

Just imagine your are a salesrep and need to write down a call - make the normal BIG dialog window so that it is convenient to write down the conversation with client.
