Hello, carol23.
There are times that the overloaded files stored in your browser are affecting the process. To check you can try to submit a spreadsheet through a private window. Here’s how:
a. For Chrome, press Ctrl + Shift + N.
b. For Internet Explorer or Firefox, press Ctrl + Shift + P.
c. For Safari, hold down Command + Shift + N.
If it runs fine on a private browser, it’d be best to clear your browser’s cache or switch to other browsers.
Please don’t feel hesitant to visit us again if you need anything else.
