Close database not available / greyed out

Hi

there is one database which gives me issues; basically the close database function is not available (greyed out). Also the other functions such as Verify & Repair, Rebuilt etc are greyed out. Cf. screenshot.
Beside this, I do not notice particular issues.
If I close and relaunch DEVONthink, the “Close database” becomes available again. I had a look at the log and I don’t find any “alert”.

Context: MacOS 15.7.2, DT 4.1.1, the database contains only indexed files (from a Synology Drive folder)

These commands are disabled while the database is synchronized.

Sorry for my late reply.

I went to Settings → Sync and unchecked the database from the list of databases synchronized via iCloud (CloudKit). The status of that database is now shown as:

“Not yet synchronized, upload database.”

The issue persists: sometimes I am still unable to close the database. For example, yesterday I added some files to this database. After that, I could not close it. I left DEVONthink open overnight, but this morning the database still cannot be closed. The only way to regain the ability to close it is to quit DEVONthink entirely and reopen it.

This does not look like expected behaviour to me. Is there anything I should try ?

For reference, the full Sync settings are shown in the screenshot below.

Any background activity (not only synchronizing) might block closing. How many files did you add? Anything in the Activity window?

I added I believe ca. 60-70 2-3 pages PDF files (I’d say less than 1MB each).

I don’t spot issues in the Activity window, is there anything special I should search for ?

And nothing in the Log window either?

No, the log window is empty

I had this problem and the unique solution I found was to quit DT (CMD+Q and reopen it).

What kind of sync location(s) do you use?

iCloud - as per my screenshot above
If I understand the settings correctly, at the moment only one database is actually being synchronized.
For the other two databases — including the one that cannot be closed — I unchecked the synchronization a few days ago.

Does disabling the sync location completely and restarting DEVONthink make a difference?

In DEVONthink, hold the Option key and select Help > Report Bug so we can look at the machine info and logs. Thanks!
