I have tried to sign-in to my account from Logos Desktop App, but to no avail. I can sign in on my other mobile devices, but not my MacBook Pro. Initially, I was signed in, but I could not synchronize anything, it always came up with an error message. I signed out, hoping I just needed to sign back in, but to no avail. I assumed that I had to buy a subscription, and I purchased the Pro edition. I tried signing in, to no avail. I downloaded the app again, re-installed it hoping that would bring some relief, to no avail. I'm at a lost on what is going on. Hopefully, this forum can provide some answers.
