Office online server (oos) is broken in chromium based browser including new Edge.
This is because of chromium removal of xhr request on page leave (v80). Hence file will not be saved when user exit the page since session will not be closed by the leaving event callback.
There seems to be no new oos release since November 2018. Surely it is due for an update right? There are still people depending on these on premise solutions.

Thanks, as mentioned by trevorseward, We need to download the latest patch.
I think July 2020 patch fixed this issue for words online.
However, I do notice the scrolling is ridiculously fast in edit mode compared to read mode. But thats another issue, so i will put up a new post separately.
Thanks @Itch Sun-MSFT and @Trevor Seward

Hi @Jason T
I noticed that the account you are using is different from the account you started to post, you should use the account you originally posted to respond to.😊
Make sure you're applying OOS patches. The current patch is https://support.microsoft.com/help/4484470.
With that being said, I have no issues with OOS and saving documents using Edge Canary/Google Chrome.
Thank you for your feedback on this issue. According to our policy, I can't test with the chromium you mentioned, but in Chrome, Edge, IE, OOS works fine.
Based on your description, I think you may have found the real reason, and it seems that the only solution so far is to use a different browser.
As you know, the latest OOS version so far is November 2018.
You can follow this website below, once Microsoft has the latest version, this page will be updated:
