Hello, what WordPress version are you using?
Does it give you any error/warning?
I’m not seeing the annotate buttons either. I have the latest version of WP.
dhscratch: I have seen some problems with users that has the WP Typography plugin https://ww.wp.xz.cn/plugins/wp-typography/
I’m not seeing the annotate buttons either. I’m running WordPress 4.5.3 but I do not have the WP Topography plug in installed.
UPDATE:
I see what the issue was now, this plug in apparently doesn’t display it’s buttons for some reason if you are using Page Builder plug in by SiteOrigin. I deactivated it and the annotate buttons appeared.
