i noticed this today (28 Mar 2021) on one of my observations (https://www.inaturalist.org/observations/72315244). megachile added a comment at 7:18 PM Central, and i received a notification at 7:19, but the comment doesn’t appear in the observation 30 minutes later (and it’s not the in the API results nor Android app observation page either):
… also i wonder if this other bug report (https://forum.inaturalist.org/t/ids-and-comments-slow-to-appear/5324) is the same kind of thing and should be merged with this one?
UPDATE: sometime between about 8AM and 2PM the next day, the comment showed up when viewing the observation. i looked at the update date of the observation using the the API, and it reflects the date of that last comment by megachile. so it doesn’t look like anyone changed the observation in any way since then.
ANOTHER EXAMPLE: on https://www.inaturalist.org/observations/41715701, someone added a comment at 5:15PM Central on 3 Apr, but two hours later, the comment is still not showing up.
