DEVONthink sync between MacBook & iPhone

*Sync suddenly stopped working (Mac ↔ iPhone) — anyone else run into this?

I’ve been troubleshooting a sync issue with AI assistance, but haven’t cracked it yet. As of Sunday morning, sync between my Mac and iPhone just stopped working entirely — no updates flowing in either direction. Has anyone else experienced this, or have ideas on what might cause it?

In DEVONthink or externally?

Also, when you have a sync issue, you should first answer these questions, where applicable:

What is reported in DEVONthink’s Window > Log?
Is there a triangle on the Activity icon in DEVONthink To Go’s bottom toolbar? If so, tap it. What is reported?

Windov > Log? DataBase “Inbox” successfully verified 2. No triangle activity icon

In DEVONthink, hold the Option key and select Help > Report Bug.

First, think about the most obvious reason. Have you renewed the update for the DT desktop version? DT 4 allows you to set up DTtoGo for free. However, the app only works for as long as you receive updates for the desktop version. So if you set up DTtoGo via your DT desktop app, that could be the reason.
