I have been developing an addin for SharePoint for a few weeks now.
Today, when I try to test my addin, by hitting F5 in Visual Studio, I receive an error HTTP 429 (Too many requests).
The addin is eventually deployed, but I can't start a debugging session.
Is there a new policy in place on O365 ?
My Visual Studio is up to date, with version 15.5.6
What can I do ?
