The GIF on that nematode observation is 24.5 MB. Not sure how the user got around the 20 MB upload limit,
I’d be willing to bet that the large file size is the source of the problem. Does the same happen when you access observations with smaller GIFs?
I usually do some size optimization before uploading, so perhaps try these:
- https://www.inaturalist.org/observations/52628358 (7.53 MB, poplar & willow borer)
- https://www.inaturalist.org/observations/54036016 (4.01 MB, cali. noct. velvet ant)
- https://www.inaturalist.org/observations/52866666 (1.94 MB, savannah sparrow hatchlings)
- https://www.inaturalist.org/observations/52506834 (0.99 MB, giant water bug)
- https://www.inaturalist.org/observations/52542782 (116 KB, pine white butterfly)
