I have the same problem and I'm at the end of my rope with Evernote Business. I love everything about Evernote except I can no longer deal with "Not Responding". I've tried almost every suggestion on this forum and from Evernote support on my account and my employees accounts. I've bought brand new, high end computers with ssd's, high memory and I still have the problem. I'm holding out hope that Evernote's restructuring of the data will fix it but I can't wait much longer. I sent a support request to see if my company's data had been migrated yet. I've been a customer since around 2012.
