When trying to authenticate OneDrive in Akeeba, when using Firefox, I am not able to log onto the OneDrive account and it simply grabs the information for my personal OneDrive account instead of my business OneDrive account. If I switch to Edge, I am able to log on to the correct OneDrive account. This caused me to waste several hours troubleshooting the issue. You might want to fix this so it works with any browser.
BTW, the backup still worked when using Firefox, it just stpred the backup file in the wrong OneDrive account.
