Hi @bert12,
A subscription to Enketo’s paid service would not help in this case.
Unfortunately, there is an issue with this plan (even if you hosted your own Enketo server). Those edit URLs only stay active for a very short period (by default 30 seconds - configurable in Enketo’s configuration - but not recommended to make much longer anyway).
A real solution here would be more finely grained permissions on the KoBo side, but that seems pretty complex. It really has to be managed on the side where the data is stored as it requires managing records (once a record is edited, it gets a new instanceID, so it needs to be effectively locked during editing). Sorry, I don’t have any better ideas to meet your requirements quickly.
