On maps, the circles that become upside-down tear-drop shapes when fully zoomed in only have a selectable area that comprises about the lower-right 1/4 of the circle and sometimes that selection area disappears entirely until you zoom in or out. This can make it difficult to click on the point. The upside-down teardrops have a very small selection area also which seems positioned just to the right of them. The close boxes seem to be misaligned at times also. It would make it easier if the entire circle were clickable and the teardrops had a larger selection area as well.
Also, on 75x75 thumbnail images, such as on the copyright info page for any given image, or in your own IDs page for the thumbnails of observations you’ve already ID’d, only the top about 1/3 of the image is clickable. This isn’t true for the thumbnail for that entire species’ profile to the right of it, however. The thumbnails on maps also function fully sometimes, then partly in other circumstances. It seems if you go to a map via “observe” they seem to work, but the maps under a taxon’s profile page have this same issue, except the top ⅓ of the thumbnail is selectable and the bottom ¼, and also sometimes (but not always) just the very center of the thumbnail. Here’s an example: https://www.inaturalist.org/taxa/984457-Pione-lampa drop down to the map and select one of the points, now try to click on its thumbnail in the pop-up dialogue box. You can see some parts of the thumbnail are selectable, and others aren’t.
