Greetings,

Error msg: “Failed database verification, please repair database”

Not sure when it started happening or if there was an upgrade or I did something to cause this. I’m not a very experienced user.  
I am using DT Pro 3.6.3 on a MacBook Pro, Model Identifier: MacBookPro14,2, Processor Name: Dual-Core Intel Core i5, Processor Speed: 3.1 GHz 16 GB Ram  
I am synching over iCloud (legacy), encrypted db  
I tried Synchronizing, verifying and repair db, optimizing db, rebuilding db & cleaning db. The error remains. I tried upgrading db to CloudKit but it won’t upgrade, I think due to the error.  
I have DTTG ver. 3 which syncs ok.

All help appreciated.  
Darrin

You might want to tag onto [this](https://discourse.devontechnologies.com/t/unable-to-repair-database-of-indexed-files/62736/) thread, or [this](https://discourse.devontechnologies.com/t/database-inconsistencies-after-upgrade-to-dt3-6-3/62749/) one. I’m not sure what’s going on, but I think now we need to wait for input from @cgrunenberg, @BLUEFROG et at.

I have the same (or similar issue): 3 databases. Two sync fine but one does not sync anymore since a day. Verify&Repair gives ‘failed’, repair database. I did (repair) but it again failed with V&R. (no orphans, but 7 inconsistencies). Running Devonthink 3.6.3 on MB Pro Catalina 10.15

Update: I deleted all 7 inconsistencies - now the database sync! Solved my own problem 🙂
