Unable to download Keynote or Numbers apps - "purchased with a different Apple ID"
I just migrated from my 2011 MacBook Air on High Sierra 10.13.6 to my 2020 MacBook Pro on Catalina 10.15.5. On the 2011 Air, I have Pages, so the update to Pages on the 2020 Pro was successful. I used the migration assistant on the 2011 Air to migrate my data to the new Pro.
On the 2020 Pro, it tried to update Keynote & Numbers. NOTE that I found both the Keynote & Numbers apps in the Applications folder (Pages was also there).
I get this pop-up message:
Current Update App
Keynote cannot be updated because it was refunded or purchased with a different Apple ID
I get the same for Numbers.
I searched the Apple forums. The only tip I could find that appears to be related said I should delete the app, go to the app store, and install it.
Well, I moved Keynote & Numbers to Trash.
When I go to the App store to download these apps, it is impossible -- the only option is to UPDATE. Well, if I don't have the app, how can I update it???
Why can't I download these apps?
Also, I don't understand the message about the Apple ID being different. I did change my Apple ID from yahoo to gmail in 2014, but I didn't download Pages on my 2011 Air until AFTER 2014.
Any help is appreciated on how to get Keynote and Numbers downloaded from Apple. I found other non-Apple sites but didn't feel comfortable downloading from them.
Thanks, Lynne
