1Password 8 data migration

I need help with transferring data from 1Password 7 to 8.  I’m using Mac.   I spent nearly an hour with the chat bot which ended with a ticket number, an escalated issue notice and a promise a human would follow up with me.  It's been 3 days and no contact with a human to help me has occurred.  I'm extremely frustrated.  I’ve tried to re-engage the chat bot but the chat keeps ending with the promise that a human will contact me.  So far crickets.  When I tried the 1Password 8 migration it did not recognize my 1Password 7 vault.  So i tried the .csv approach.  Only part of my data transferred; the secure notes and card data were incomplete and appeared corrupted.  I’ve been a 1password user for nearly 20 years. Any advice?  Thanks.
