I am using the BB builder and theme. When I am in page builder mode and begin to edit the page all is well, but the longer I edit the page it begins to slow and then eventually slows to a crawl and almost freezes. The only way to fix it is to save the page and go back into edit mode.
Sorry to hear about the issues! I wonder if a plugin is conflicting or a piece of content. That is abnormal behavior for sure! To start, can you disable any caching you have enabled and then give it a shot? Also, is the incident only limited to a single page or several? You may even want to give the plugin deactivation route a shot anyway in the event there is a 3rd party plugin causing issues. Let me know how any of the above goes and we’ll go from there!
