Read the connection status
Connected means Taiega has a usable authorization record. Needs attention or expired means the provider rejected a refresh or revoked the grant. Reconnect renews the same provider identity; Add account creates a distinct connection.
If Add account returns immediately
Confirm the button started the Add flow and not Reconnect. The provider may automatically authorize the account already signed into its browser. Use the provider’s account chooser or sign out of that provider session, then begin Add account again.
If the provider says application not found
The OAuth application may be unpublished, deleted, restricted to approved users, or opened from an outdated authorization URL. Return to Taiega and start a fresh connection. If it repeats, record the provider, time, and visible error for support.
