There is an issue with indexing. I have tried all the possible fixes without luck - wasted so much time. There is an error in Evernote's code as is usual with every update.
Evernote just gets worse and worse. So many bugs on every release, no attention to detail, unhelpful support, stupid new UI updates without fixing glaring problems. It's a shame it's so hard to move to other software. I've downloaded Notion app and am now trying it alongside Evernote.
Response from "support" after a few days:
After speaking with our technical support team about this issue, they advised that our development team is already aware of the problem and working on its resolution. We’re working on a fix that should be in an upcoming release, however there’s not an estimated date on when it will be available. I know this can be frustrating, especially if Evernote isn’t making a positive impact on your workflow and do apologize for the inconvenience.
If you have any further questions, please let me know. Thank you for your time and patience.
