Today I upgraded to Evernote 10.60.4-mac-ddl-public (20230803182206). My previous version supported local notebooks, so I followed the instructions at https://help.evernote.com/hc/en-us/articles/209005107-Convert-local-notebooks. I chose "Check for Local Notebooks" from the Tools menu, then in the "Local notebooks found on this device" dialog, I clicked the arrow next to my local notebook, which contains 563 notes. Partway through the "Exporting Notes" process, the "Local notebooks found on this device" popped up again. If I click the arrow next to my local notebook again, I'm stuck in a loop of the same behavior. So I cancelled out of the dialog. Then I tried to import the resulting .enex file, and got the message: "Failed to Import Notes. Your import had an error. We were able to import 103 notes to (Imported) Pandora Notebook before this error occurred." Also, the the imported notes are all dated 1/20/1970. How can I recover the remaining notes from my old local notebook?
