Hi Community!
A few of you migrating from the old experience have run into this: reuses submitted under the old experience now show up under Requests in the new back office, but clicking "view asset in catalog" returns a 404 — and sometimes the Showcase content isn't even visible/editable from the back office.
🔍 What's actually happening
This isn't a migration bug : it's a permissions issue. Reuses are migrated into Showcases, which are a type of "external/other asset." If your admin group doesn't have permissions on that asset type, you won't be able to see or open them, even as a super admin.
✅ Fix
Go to your permission/group settings and make sure the relevant group has access to external/other assets (not just Datasets). Once that's granted, the migrated Showcases become visible and the 404 goes away.
