When I was done annotating, I erased all my changes. But when I checked the original PDF document, the annotations were still there! So Kami saved my annotations even though they were erased.
Sorry for the late reply, if you waited 3 minutes and refreshed the page, did you see the annotations get erased? It can take up to 3 minutes to save if you’re relying on auto save. If you’re doing a manual save, then it’ll be significantly faster.
