Sorry for not being precise enough. With core team I meant people who have deep technical and security knowledge of Nextcloud such as Lukas Reschke (where is he btw?) and not someone from PR/marketing.
On what facts do you base that this bug is hitting only a single home user? Please cite your sources here and your analysis how you found out that this bug is only affecting one single home user.
What about this server-side encryption issue (503 Encryption not ready: multikeydecrypt with share key failed · Issue #8349 · nextcloud/server · GitHub)? It is open since February, seems to hit more than one user and does not have any solution or fix yet.
I take the opportunity here to thank you for your answer and in advance I would like to thank the developers for taking seriously and fixing these type of server-side encryption bugs which can lead to data loss.
Please cite the sources in the official Nextcloud documentation where these recommendations you are speaking of are written in clear text?
I checked the relevant server-side documentation in the admin guide (e.g.: https://docs.nextcloud.com/server/13/admin_manual/configuration_files/encryption_configuration.html) as well as in the user guide (e.g.: Encrypting your Nextcloud files on the server — Nextcloud 13 User Manual 13 documentation) and could not find anything about this recommendation of using server-wide key and not per-user key you mention.
Again thank you very much all in advance for focusing on fixing current and old serious issues such as server-side encryption instead of new fancy product-marketing features.
