I got the free book of the month, plus the others too. Mindlessly, I decided to 'read' them on my Logos Bible app. Only one showed up. Sigh. Hard to refund a freeby.
But while I was wasting time, I took a look at the Logos Store (in the app). You can sign up for the Connect subscription. But they also offer a cheaper one for $4/mo. Of course, I naively wondered what was in it. So, I googled:
site:logos.com "bible study bundle" and "bible study tools (monthly subscription)" .... from the app's offer.
No mention in Logos.com. Faithlife.com even more sparse.
But Apple is happy to oblige, setting up the mystery subscription! I was afraid to see if anything downloads.
Books.Logos,com also has a neat 8,000 volume theological subscription.
