-We recommend checking if your Nextcloud provider supports E2EE, otherwise you have to trust the provider to not look at your files.
+!!! danger
 
-When self-hosting, you should also enable E2EE to protect against your hosting provider snooping on your data.
+    We don't recommend using the [E2EE App](https://apps.nextcloud.com/apps/end_to_end_encryption) for Nextcloud as it may lead to data loss; it is highly experimental and not production quality.
