It keeps showing this issue when I try to approve the bills and POs that are before the closing date: "Something went wrong and we couldn’t approve Bill "bill ref."

I understand how challenging this is for you. To check if this is a browser related issue, I suggest opening the site in an incognito or private browsing window to bypass any stored data that might be causing the error. If that doesn’t work, use a different web browser to see if the issue is browser-specific.
