Things going missing on the Open Geography portal (https://geoportal.statistics.gov.uk/) that are there but need to be reshared again

[MattJinman]

One really annoying thing on the Open Geography portal (https://geoportal.statistics.gov.uk/), is that boundaries go missing for no apparent reason and I have to reshare them, even though it has been shared previously. It’s having to reshare a boundary set that was already shared.

Take the Scottish Parliamentary Constituencies (https://geoportal.statistics.gov.uk/search?collection=Dataset&sort=name&tags=all(BDY_SPC))

But yet when I go to ArcGIS Online it is already shared

So I basically have to reshare it again for it to reappear and this is the result on the Open Geography portal

Is there anyway we can stop this happening?
