Fix a social post that Sequence cannot import

A valid supported post completes capture, or you have enough context to report the specific source limitation.

Open the URL in a signed-out browser. The post must still exist and be publicly reachable.

Copy the direct post URL. Remove tracking parameters and avoid profile, embed, redirect, or shortened links.

Use a currently supported public social post source. A valid URL does not guarantee that the source permits capture.

Submit the cleaned URL again. Do not create repeated copies while an earlier capture is still processing.
