My team is also experiencing this issue. We've done the same as everyone in this thread - trying different browsers, clearing cache and cookies. It has not crashed yet in Chrome incognito mode.

Is there a dev team working on this from the QBO end? It's not a coincidence that a Google search only brings up this thread. Cleary this is an issue on the QBO end that came up in the last couple of days.
