Edits to Collabora Online spreadsheets not getting saved; issue may be linked to "The server encountered a nodocloaded error while parsing the setviewreadonly command" error message

Hi everyone, I was using the Collabora-based NextCloud Office tool, together with NextCloud AIO v13.2.1, to host some spreadsheets that I update on a regular basis. I found in late June that, after updating a spreadsheet, my changes would sometimes get lost when I next loaded the document. This issue occurred on both the NextCloud Android app and my mobile Android web browser; I don’t think I’ve had it happen on my Linux Mint desktop’s web browser yet.

I’m guessing this issue is linked to the following error message: “The server encountered a nodocloaded error while parsing the setviewreadonly command.”

I’ve been trying to make sure to save the document before exiting out of the spreadsheet viewer, but that doesn’t seem to help.

Any tips for resolving this issue would be greatly appreciated. Thank you!

(I've temporarily switched over to Euro-Office and haven't had any issues just yet with lost edits, but I'd love to get the Collabora-based setup working again, as its mobile spreadsheet editor works better than does Euro-Office's.)

Start by reproducing the lost spreadsheet edits with Nextcloud AIO v13.2.1 and the Collabora-based Nextcloud Office tool on the Android app and mobile browser. Check whether the “nodocloaded” error appears while parsing setviewreadonly, and verify that edits remain after saving, closing, and reopening the spreadsheet.
