Bubble is loosing what I have done

Today I’m facing a lot of problems working with Bubble.

Every change I make is loose after I change to Design or Workflow. And also it doesn’t reflect when I test the app. It still continue working as I didn’t make the change.

Is anyone else having this problem?

Yes! I just went to check something and my live reverted back five days??? I’ve pushed several times in the last five days.
