Latest "Numbers" update
I created a "Work Flow" at my job using numbers (which are shared accross the plant with multiple departments), when I started doing that I bought older devices (ipad mini 2, ipad air, etc") then I started using my imac which was updated to catalina... some day dont know when there was an update to "numbers" which render all of my other devices unable to keep using all of the sheets I created, every time i tried to open them it prompted me to update numbers or edit a copy of it (this last one not a choice since everyone at the plant have access to every sheet and would create multiple sheets with different data)... so I tried to update "Numbers" with no result since all of the devices mentioned at the beginning cant update pass IOS 13... so how do I go back to a previos version of numbers on my imac to be able to still use all of the devices across the plant... and how do I do so when other people not in the plant can still access my sheets who would have the update "numbers" and won't mess them up?
