Just want to tell that I'm working on a better synchronization feature - I think it will speed up the sync dramatically.
Basically FindVUK will store a hash of the file after a full-sync and the date of the sync and as long as the file is not modified externally it will just request delta-files for synchronisation (such a file is around 200kb for the last 60 days).
The server part is already done - see here:
Delta File since 2020.05.04 23:00:00
In case the requested date is older than 60 days or in the future or cannot be parsed at all, the full file is offered instead. The delta file includes all entries that got either created or modified in this time area.
Next I'll implement the required changes in FindVUK - but this will take a few days.
Small note:
It's also possible to use relative deltadate attributes - e.g. this here will always return a file with all entries changed during the last 24h:
Changed entries in last 1 day
