I have a new alpha build with the fix and avoids the delays seen on NAS for users with massive extras.
I can send it to users that have the high number of extras as showing when doing this query on the database
select count(metadata_item_id),metadata_item_id from metadata_relations group by metadata_item_id order by count(metadata_item_id) desc limit 20
The alpha build willl be 1.25.4.5396 or later
(I would not be able to provide an alpha update process for docker - so for other platforms only)
