I was working on a campaign, using a very simple basic template. Initially, I started noticing huge lags when trying to upload images, which can take up to 2 minutes to get uploaded. Then today at one point it went go through the whole loading screen after having selected the picture I wanted to upload, but then when the loading screen was over no picture was there. I tried it again a couple of times and it kept doing the same. So I saved and refreshed the page. Nothing. Then I went back to the home, and tried to re-open the campaign from scratch. When I see the preview of it, it looks fine but when I click on "edit content" and it opens up the page the whole content I worked on (text, images, etc.) is gone. And the template is back to blank. I tried signing out, from a different browser, refreshing the page and it kept happening. Now it doesn't even load the campaign anymore, when I try to open it it just gets stuck on loading forever.

What's going on??
