What happened instead?

No one sees the posted image or file. Getting error msg "Error downloading image" or "Erreur lors du déchiffrement de l'image" for images. Getting error msg "Error downloading file" or "Erreur lors du déchiffrement de la pièce jointe" for a file.

Please see #28011 (comment) for specific guidance.

Backward compatibility between versions is a key feature to users who do not always want / need to upgrade. In this case, the latest version breaks the backward compatibility concept. The Element team should make it clear in their comments / readme when this feature is broken in a version, and minimize occurrence of breaking this key concept. So sad for my Windows 7 user ....

Similar to #28016 .

Same issue here (also Linux web browser(latest brave beta)), per the comment above i see about a service workers problem, service workers are disabled by default on the browser and not likely to be re-enabled here, so is there a way to get the old behavior since it worked with them disabled up until a week ago?

Edit: just realized all old images still load. Only recent stuff isn't
