1 account, multiple devices? “yes, but” - there’s no terms-of-use or technical restriction barring you from adding your account to more than 1 /e/OS device. Contact / Calendar / Tasks will work, but file sync isn’t geared to be used with multiple /e/OS devices. It will still mostly work but it will get uncanny on filename collisions or modifications to the same file.
Stability: you’re asking because of your last thread @e.email - "server certificate not trusted" ? both domains are served from the same infrastructure (mail.ecloud.global) so no difference in principle - config issues can hit one domain first before the other though.
I have a fairphone 3+ with murena account. I sync everything without problems also on my iPad and on my two Linux laptops. Sometimes when I try out new systems on virtualbox, I also installed murena as online account. Without problems
thanks, clarified that bit from “devices” to “/e/OS devices” - I only worried about photo uploads, but misremembered - it’s not subsequent numbering. OpenCamera timestamps to seconds, a collision is unlikely unless you have 4 hands… unsynced edits to the same file will be an issue though
I have used my eCloud / Murena account on several devices with very few problems
phones running IodéOS and LineageOS for microG, using DAVx5, ICSx5, and NextCloud Desktop client and Notes apps to handle sync
Computers running Linux and MacOS, using NextCloud client for files, QOwnNotes for Notes, and Thunderbird for Contacts and Calendar sync
It should all work fine, because Murena is basically a hosted NextCloud instance, although I believe it is ‘tweaked’ slightly, and often lags behind the latest release of NextCloud
