Backfill missed comments from the Instagram API when the webhook never arrives

Meta does not send a comment webhook for every comment, so a large share never

reach the automation. On our account 311 comments contained the trigger keyword

and only 135 were processed. 176 were never seen. Yesterday 57%, today 70%.

When it does fire it replies within about 8 seconds, so this is not backlog or

slowness. Identical comments on the same post minutes apart either fire

instantly or never at all.

Because the comment never arrives there is no log row, no error and no skip, so

it is invisible until a follower asks why they got no DM. It is also not comment

filtering, the missing ones sit in the public comment list and Hidden Words is

off.

Request: have automations reconcile against the comments you already hold. The

Comments tab clearly reads a cached snapshot of the full comment list from

Instagram's API, with a lastUpdated stamp per post. Every comment the automation

missed is already visible there. So the fetching exists, nothing just compares

the two and runs what was skipped.

Even a 15 minute sweep over posts from the last 48 hours would close most of the

gap. Logging which comments came in via the sweep would also make the size of

the gap visible instead of invisible.
