Does anybody else experience this?

1. You are entering bills / expenses
2. All has worked for the first 5 times you do this....enter the bill and then attached the PDF receipt
3. Then the 6th one....you just CANNOT attach the file
4. You refresh the page.....nope - does not work....
5. You save the Bill with no attachment and then reopen it to attach the document....does not work 
6. you try again....no luck
7. YOU THEN SHUT DOWN THE BROWSER AND ALL AND START AGAIN AND IT MAY WORK.....

This is so annoying......and happens in Edge, Chrome, Firefox......
