Errors on Monday.com

Wondering if anyone gets a 404 error or blank page when click a task on monday.com workspace? When I clicked on some tasks , I got popped out of task and could not access it, and then a “problem message” was shown on the screen. And it still can’t work after refreshing the website for many times. Furthermore, when I input a draft to a task but it can’t be saved. Could you give any solutions or suggestions? Thank you.
