I can't disable Restrict Sign In on OneAuth App

I can't disable Restrict Sign In on OneAuth App

I had downloaded the One Auth App and enable restrict sign in, but then I decided to delete it since I didn't find good use for it. However, a ny time I attempt to sign in to check my Zoho emails, an error tells me to go to the OneAuth app and disable restrict sign in. I then downloaded the OneAuth App again, but it doest let me sign in either, so I am stocked without been able to use my Zoho Mail.

Any suggestions? Please help.

Thank you!!!
