A finished article is never held back. If your CMS cannot take it, for any reason, the article publishes to your GrowGanic blog and moves to your own site on its own once the connection is healthy again. You are told where it went and why, and nothing waits for you to notice.
Connections that fail in a way that proves the credential is dead, a revoked token or a removed app, are switched off so nothing keeps calling with a credential the provider has already refused. You get an email naming the destination and what to do. Everything else, a timeout, a rate limit, a brief outage, leaves the connection alone and retries.
When the refusal is of a grant you approved in one click, we delete it from our database there and then: the provider refusing its own token is the provider telling us the grant is over, and getting it back is one click on Connect. A key you pasted is kept instead, because a refused call does not prove a pasted key was revoked. A self-hosted site very often refuses for a reason that has nothing to do with the credential, and keeping it is what lets Test repair the connection with nothing re-entered. Disconnect if you want a pasted key removed.
Clicking Test on a connection repairs it as well as checking it: a connection that passes is switched back on and picks up the articles that landed on the hosted blog meanwhile. A failing test never switches a working connection off.
