After a motherboard replacement I can't upgrade to latest version of Numbers
In OS Catalina, Numbers is v. 6.2.1. Files open but when I attempt any action, the records "disappear"
Tried restoring a file from Time Machine and from an old laptop, but the problem remained.
Upgraded to OS Monterey 12.3. Problem persists and can't upgrade to latest v of numbers.
MacBook Pro 13″, macOS 11.6
