Thanks so much for the follow-up @Chimwemwe and I'm so glad you're back up and running!
We traced this back to an issue with our Cloud upgrade process for v2025.4.4. If any other Cloud customer has been affected by this, please get in touch so we help make sure all your Entities have been correctly created and updated.
Self-hosters were not affected by this issue.
It looks like @Thalie is experiencing something different, I'm still looking into it and will update on the other thread!
