Team Inbox is not working AGAIN

Team Inbox is not working AGAIN

I like Team Inbox in general. It makes using a collaborative inbox easy - when it works.
The problem is that it doesn't work at times - and it seems to not work, a lot.

It's not catastrophic failure, it's little things. 
Unable to send messages
Unable to receive messages
Unable to search
Integrations with other Zoho products fail.

There's also the short fall in functionality 
* Bulk delete of emails is laughable. At best you can do 240 at a time, IF that works. I have been limited to doing 150 to 200 for months because there's a problem there. 
* No "empty deleted mail function".  So I still have email in the deleted folder that doesn't disappear unless I do it 240 at a time.
* No "forward to" with attachment functionality.

Today is no different when it comes to this Business Grade solution not working.

First, email delivery seems slow.  Hard to test that, so I'll wear it.

Second, Go to the search function and look for an email - no results.  You get a message that nothing was found.  I KNOW there's messages there, because I was looking at them yesterday.  Check for a message I know is there, nothing found.

Click on the SPAM box and it's empty.  That NEVER happens.

Looking at Developer Console, there's a number of JavaScript errors - mostly Server 500 or 404 errors.  This would indicate that it's the Zoho Servers that have a problem.

Log out, clear cookies, log in.  Problem still exists.

I check the mobile app and get exactly the same results.  So it's not the PC and it's not the Phone. It's the app and the servers.

After spending 40 minutes on the phone with "tech support" and being asked some questionable questions, I get told that it has to "go to the developers" and they'll get back to me as soon as possible. 

All this time, I'm not actually doing the work that I need to do to run my business, so I'm losing money here.

This is a business grade system. I pay for a business solution. I don't feel that business grade support is provided.
