Page is not responding after add a report to a Book
I tried to add a report to a Book, but after I clicked the add button, my page was not responding.
I tried in new private/incognito windows and cleared the cache, but it's still the same.
Previously, I tried to open the Book and open it as Excel, but the loading takes forever.
So, I decided to create a new one and then this happened.
Is this a bug or what?
Thanks in advance.
