iPad atomic web browser problem. Not remembering last session

Anyone else having this problem? When I open the app it used to just open all my tabs from last session. Now it doesn't do that anymore. I have went into settings and chose all of them but all it ever does now is open with one blank tab and I have to backgrounder it if i want to keep my tabs open

Any ideas?

 

Thanks zuker. I didn't even know that the private mode was on.

Next problem: I turned off private mode and now o cant open the app. Well that is not true. It opens but it is dark around the edges and light in the center like a error box is going to co e up but it doesn't.

Any ideas? Id hate to lose all my bookmarks etc by having to reinstall.
