"To open this spreadsheet, you'll need the latest version of Numbers."
Hi - when trying to open a certain Numbers file on my Mac (Catalina), I’m getting a “To open this spreadsheet, you’ll need the latest version of Numbers” error box that never used to pop up 1-2 weeks ago. Other threads mention that one culprit for this is opening the file in iCloud.com in the latest version of Numbers. However, in my case, there are other Numbers files I’ve opened recently via iCloud.com that still open just fine on my Mac. It only seems to be this one particular file (which happens to be password-protected), the contents of which havn’t changed much in the last 2 weeks (it’s not like I started using any Monterey-only features on the iCloud.com version in the last 2 weeks). Any suggestions?
