It should load
It doesn't load

vendor/.../build/ directories are not existent in the released packages.
Could the markdown editor somehow interfere with our js files? Apparently something breaks requirejs.

Which file/directory is needed?
Oh, do you have debug mode enabled? Indeed some files are missing, but it should not affect the bundled mail.min.js file as it includes everything.
@ChristophWurst Ah thanks. It works fine after disabling files_markdown and debug mode.
Which file/directory is needed?
When debug mode is enabled it tries to fetch js/vendor/backbone.radio/build.backbone.radio.js and js/vendor/ical.js/build/ical.min.js which do not exist.
The following errors appear with disabled debug mode and enabled files_markdown app:

I'd say that's a bug of the files_markdown app. Its js should not be loaded on other app's pages.
When debug mode is enabled it tries to fetch js/vendor/backbone.radio/build.backbone.radio.js and js/vendor/ical.js/build/ical.min.js which do not exist.
I messed up the rsync command in the Makefile, apparently excludes are not relative paths but patterns. I wanted to exclude the build directory of the app, but that also excluded any build dir in the directory tree.
Jep, had exactly the same. Deactivated debug now.
Same here, mail app version 0.6.2. is not loading after update, I tested in ownCloud 9.1.3, this is the error log from the browser console:
Die Ressource von "https://domain.tld/apps/files/" wurde auf Grund eines nicht übereinstimmenden MIME-Typs blockiert (X-Content-Type-Options: nosniff).
Error: Script error for "ical", needed by: service/davservice

Is debug mode enabled? Do you use the markdown app too?
Loglevel was set to 2 in config.php.
But I think my testing cloud is broken, I did updates to ownCloud 9.1.3 in production clouds which also included mail update to 0.6.2 and here the app is loading.
My nextCloud is not up to date (yet) …
Loglevel was set to 2 in config.php.
Log level and debug more are two different config values. The latter is enabled/disabled by 'debug' => true, in config.php.
Yes, debug is set to true.
I have to re-order all my testing and production clouds. They are too many and I am loosing the overview … ;-)
I've uploaded a fresh nightly build that contains the fix for this issue to https://apps.nextcloud.com/apps/mail 🚀🚤💨
I can't enable Mail 0.6.2 (cloned from Github)
Error: it makes the server unstable

That's no surprise. You're missing a lot of stuff if you just clone the repo. Check the readme on how to set things up for development. If you just want to use the app either use a release or a nightly build.
I don't know how to install a nightly build, sorry.
How can i achive that?
apps dir of your Nextcloud (make sure to remove any previous version first)Installing apps via the app store is the recommended way though :-)
any further questions should be asked in the forum https://help.nextcloud.com. This is the issue tracker. Thanks
OK.
cd /var/www/nextcloud/apps/
rm -rf mail
git clone https://github.com/nextcloud/mail
makes the server unstable as mentioned above.
Unpacking the zip file

to
/var/www/nextcloud/apps
creates a folder
/var/www/nextcloud/apps/mail-master
Next step is the update from 0.6.2 to 0.6.2

After updating and enabling the mail app, it still does not work. Still 2 hourglasses. debug=false in config.php, Markdown editor is disabled.

With enbled Markdown editor



Disabling Piwik does not make an enhancement.
Please use a release from the appstore apps.nextcloud.com. Downloading the source zip is more or less the same as doing a git cone – you're missing many important files.
Also not working. Still 2 hourglasses.

I tried enabling the app on a Spreedbox running Nextcloud 12 and I get the two hourglasses:
