I have been updating a StoryMap since April 2022 and haven't received this error until now. The StoryMap includes 15 slideshows of about 25/35 photos each to click through oblique photos. I was in the middle of adding photos and all of a sudden getting this error message. Any photo I try to add now is no different than any others I have successfully added in terms of size/resolution. Even if I try to add text I get this message. I tried logging out, clearing browsing data, and don't know where to go from here.
