Same issue for us, started this morning. All tables come and go, but I can’t see it in any delete-history. When re-loading the page from scratch, they sometimes comes back. 

Problem also presenting in Objects not behaving normally on the Board. For example trying to drag them around a Board to move them from one location to another only results in the Object returning to its starting position.

In my experience Refreshing the Browser restores normal operation.

Sadly, this happened to me for the first time yesterday (that I'm a ware of). 

I had a board open for a while (opened same day) with several tables. When I came back to the browser tab, the table that was in my viewport was gone. It was immediately obvious as all of my tables were top-alighed left to right, and now there was an empty spot. 

I tried zooming in/out, in case it was a rendering issue, but nothing. Luckily, after I refreshed the page, it came back. This was not a synced table/copy, an original with copies, and I'm 99% I created it new on the same board. 

I'm not going to lie, things like this scare me 😱

Hi everyone, thanks for sharing your experiences. 

This behavior with tables disappearing is a known bug our team is aware of. They’re actively working on a fix. In the meantime, refreshing the browser often temporarily restores the tables.

We’ll update the community as soon as there’s progress. Thanks for your patience!
