solnk schedules post-metric snapshots once per day. Follower snapshots are also scheduled daily for platforms where the connected API exposes follower counts.
You can request a refresh from a post's analytics detail page. Platform processing and reporting delays mean a new post may still take up to 24 hours—and occasionally longer—to return complete metrics.
X is handled differently because each official API read has a cost. Pro and Premium include a limited number of X post reads; repeated refreshes of the same post on the same UTC day reuse the stored result instead of spending another customer allowance read.
