Zoho is creating values

For many decades I have seen companies come and go. Zoho appears to be doing everything that google is doing. I wish them luck on taking on google and reaching the same size. Zoho I have used several of Zoho platforms and it is always a pleasure to deal with Zoho. The name brings good experience and the after you experience Zoho you want to say nice thing about it. This is how relationships should be.

Push notification to sign in to the app

Whenever I try to login to the app, it says I need to accept the push notification ... IN THE APP ... which I cannot login to without accepting the push notification that I can only receive if I’m already signed in but I can’t sign in because I can’t receive the push notification IN THE APP I’M TRYING TO SIGN IN TO.

I LOATHE Zoho and this app for this single reason, and would NEVER recommend it to anyone. I have to deal with this because my company uses Zoho, otherwise I’d never go anywhere near this OneAuth app or any Zoho services for the rest of my life.
