Show all content in excel tab online (Mac)

Hello, Sorry for posting this silly problem but I can't fix this. Somehow all the content in my xls file online has gone away and I'm not able to show it or see it again. If I refresh the page, it will showup for few seconds and then, disappear, I can only see this.

Of course in my mind I have changed nothing, but something must have happened without me realizing.

I've tried so far:

• Deleting cookies
• Restarting several times
• Opening the link in Incognito mode
• Selecting all the document with the little triangle and trying to show all files and all rows, also trying the shortcuts for this, in my case cmd+shift+9 and cmd+shift+0

If I download the file locally, I can see it all, but it is more convenient for me to use the browser, and quicker also.

Any help is appreciated. Thank you.
