Good morning everyone, I hope someone has seen this before or can offer some assistance regarding what may be happening here. Recently I have noticed that my menu links will disappear at random. When opening the website tab, all pages and links are moved to the "not linked" section. This seems to happen overnight at random. It has happened twice this week with no explanation. I have rebuilt the website each time and saved changes to any pages I adjusted. I have also tested functionality on different browsers to make sure the menu is there, and each time everything looks to be fine. The next morning it is all reset again with no explanation. Has anyone seen this before? Is there something I may be missing here? I have been using Squarespace for almost 5 years and have never seen something like this. Thank you in advance for your help!
