Thank you for responding Ambucias.
Fair enough on the 7-8 window for deleted Gmail accounts, no worries. However, as far as finding entry to my Yahoo account, I don't think the bird is fully fried as of yet. I understand the typical basis of the concluding account key blockade, but I’m interested to pursue further.
I’ve maxed out the 24 hour attempt(s) to log in, and it very well may be locked for other security reasons. I know the account is not demised, so later I'll utilize my Yahoo sports fantasy app on my phone, as there are options to log in via other types of Yahoo mobile apps that are not directly for the email account. I’ll have a read into the joined entity of Yahoo+AOL= "Oath" by Verizon privacy info sites too... should be a hoot to see the changes since the 2017 merger.
For others who may be in a better position to recover than I, Yahoo has a page worth looking at for fix issues with the account key: https://help.yahoo.com/kb/account/questions-issues-yahoo-account-key-sln25921.html?locale=en_US&guccounter=1
and a very thorough fix page on this site: https://ccm.net/faq/36332-how-to-recover-your-yahoo-mail-account.
I’ll also take a crack at contacting a Y/O/V-Rep which will prolly be pointless, but at least I’ll have tried everything possible. The account will be destroyed anyway if it is dormant for 4 months or whatever. It is what it is.
