ALL form submissions, even new ones, are wiped blank after transfer to EU

Further to my question yesterday, it seems that after using the "Transfer to EU" facility, not only have all the past form submissions been wiped blank, but even new form submissions are now showing only a timestamp, with all other fields blank. Any ideas?

It seems to be a permissions issue of some kind. I am a "sub user" on the account, and the account owner can still see the full content of all the submissions.

It looks as though the "Transfer to EU" process needs to be run by the account owner; running it as a "sub user" just seems to have lost my access to the submissions, without actually transferring the form data. The account owner still sees the submissions at the non-EU Jotform web address.

Resolved at Jotform Support's suggestion by having the account owner remove me as a sub user and then adding me back. All submissions are now visible.
