Every time I logon to the Zoho Android App, it loops back to the logon page (no error message)

Hi there,

Has anyone else experienced problems logging onto the Zoho Android App?  It's accepting my email and password, but then loops back to the logon page.  There are no error messages regarding the email or password - just a very frustrating loop.

If anyone has some advice in this regard, I'd be very grateful to hear it!

Many thanks in advance
Sharon
