Anyone noticed an issue with Play Books opening at the wrong page? After I'd been reading on my Nexus 7, I opened today on my S4 and it opened about 50 pages too far forward! Also, on both this and the S3 recently (ie last week!) when I opened on the Nexus it I got the message "it looks like you've read this on another device..." etc etc and wanted to go far too far forward, often when I'd not read it on the S3/4 anyway! (so this is a Play Books problem, I guess - though this morning was down to S4 alone).
