Numbers: no recent versions
for a Numbers file which I edit about once a month, I have versions ("File > Revert To > Browse All Versions...") from December 2021 until July 2022 - then the history ends, no more versions since July 2022. The file is in an iCloud-synched folder, it wasn't moved or alike since its existence.
What could be the reason for this? Is there a chance, that recent versions exist, but for any reason can't be accessed by me?
