I don't thing nextcloud 12 is the issue here. Simple the old used "caldav" application and the connected AndroidCaldavSyncAdapater is not working anymore.
I've removed the users everywhere as well as the application. I've switched the phone to use the DAVDroid installable via F-Droid.
The setup is so easy I won't write a howto section here.
Just be fair and donate some money to DAVDroid since the application is working out of the box.
Just figured out that my calendars in thunderbird where not working anymore after the nextcloud 11.0.0.
A quick look and comparison I spotted the change, "caldav" changed to "dav" in the url.
In thunderbird, you can change this quickly. Stop thunderbird and edit "~/.thunderbird//prefs.js". Search for "/caldav", replace it and thats it.
I just migrated my installation from owncloud 9 to nextcloud 9.0.50.
Only one thing is not working, the notes application simple shows me an empty list of notes. beside that, it is more like a new theme.
At the moment we only support manual migrations from ownCloud 8.2 and 9.0 to Nextcloud 9.
To do that please follow the usual upgrading steps:
* Delete everything from the ownCloud folder except data and config
* Download the Nextcloud 9 release from https://nextcloud.com/install/43
* Put the files into the folder where the ownCloud files where before
* Trigger the update either via OCC or via web.
I did the following steps.
make a backup of your database
log into your server and cd to the owncloud path
assuming your installation is in the directory "cloud"
cp -rv cloud/config nextcloud/
cp -rv cloud/data nextcloud/
mv cloud owncloud
mv nextcloud cloud
enable the apps you want

I created a small upgrade.sh script. Here it is.
begin of runtime environment validation
if [[ $# -lt 1 ]]; then
echo "invalid number of variables provided"
echo "upgrade.sh "
if [[ -d backup ]]; then
echo "backup directory sill exists"
end of runtime environment validation
begin of local runtime variables
end of local runtime variables
begin of downloading new version
end of downloading new version
begin of making backups
tar --ignore-failed-read -zcf "public.$LOCALCURRENTDATE.tar.gz" public
./occ maintenance:singleuser --on
cp -rv public/config backup/
cp -rv public/data backup/
mv public $LOCALPUBLICBACKUP_PATH
end of making backups
begin of upgrade
mv nextcloud public
cp -rv backup/config public
cp -rv backup/data public
./occ maintenance:singleuser --off
echo "enable the apps you need with ./occ app:enable "
end of upgrade
