Codebook Cloud failing to sync

For the last week or so Codebook Cloud sync has not been working for me.

I am running the latest version of Codebook on an M1 Macbook, M1 Mac Mini and iPhone 15. I’ve tried signing out of Codebook Cloud and signing back in, but sync still won’t work: I get the red cloud with an “x” in the lower right corner.

When I sign back into Codebook Cloud, it says my subscription will renew in July 2026, but there is a message in the lower right corner above the cloud saying that I don’t have a valid Codebook Cloud subscription.

@Newton991 Thanks for reaching out to us on Discuss and sorry to hear about the trouble with Codebook Cloud. Could you reach out to us at support@zetetic.net so we can get some additional information and look into this issue and let us know which platform you are seeing this error on, thanks!

Hello,
Thanks for answering so quickly!

My problem, as I described in the forum:

All attempts at completing a Codebook Cloud sync have been failing for the last few days for an unknown reason. I was having problems with three of the devices I use (our family has CB on all their devices and we share all our passwords, etc.):

M1 Mac mini: Tahoe 26.2, Codebook from App Store running 5.3.0 (4388)
M1 MacBook Air: Tahoe 26.2, Codebook direct download running 5.3.0 (4388)
iPhone 15: iOS 26.2, Codebook 5.3.0 (4390)

I just did an integrity check on the database on my iPhone and there were lots of fixes. I also compacted the database (I had compacted the database on my Macbook earlier). After I did those things and signed back into Codebook Cloud, the sync on my iPhone appears to have worked.

I tried the same on my other two M1 devices and still get the failed sync icon for both of them. After I sign back into Codebook Cloud on the Macs, I get the message that my subscription will renew on July 30, 2026 but the Cloud sync icon at the right corner says I don’t have an active Codebook Cloud subscription.
