This has come up several times (e.g. https://forum.inaturalist.org/t/metadata-takes-forever-to-upload/2615) so thought I should make a feature request.
When uploading images on the web, observations are stuck for a long time on the message “Uploading metadata…”. This seems to be misleading, AFAICT it is actually uploading the photo when this message is displayed. If the message was changed to “Uploading photo…” or similar it wouldn’t be as misleading, and would indicate what steps the user could actually take to reduce the loading time (i.e. reduce photo size or improve connection speed).
