Has anyone noticed the posts with iPhones & iPads using the Yammer mobile app where pictures taken using Live Shot are not able to upload or get published. The new version 11 iOS has some built Live shot like features that make the image files not display correctly unless the uploader first crops them or edits them in some other way. Does Yammer have any guidelines on this issue?
I'm not familiar with Live Shot, but I've read about issues with the new high efficiency format. If I were you, I'd just try to disable HEIC and see if that solves the problem. The path to get there is settings > camera > formats. Please let us know if this is helpful :)
