Remote calendar (link to .ics) at ecloud.global calendar doesn't show up in phone calendar app
Summary
You can easily add remote clendar (ie. holidays at https://www.thunderbird.net/en-US/calendar/holidays/ ) to ecloud.global calendar, but those doesn't show up at phone calendar app. It would be nice that calendar app could sync that added calendar information from ecloud.global calendar to phone. This would also be related that every added calendar at ecloud.global should be possible to see at calendar app with the name & color setted at ecloud.global.
Description
Who will use the new feature?
I don't know would this be new feature or the way calendar should sync by default. But this would simplified usage of calendar for every person who use calendar at both, ecloud.global & from phone app, possibly also synched to gnome calendar or similar.
What is the target of the new feature for this user?
To simplify using same calendar information on multible devices by adding subscription link to calendar information to only one of those calendars.
Why this user would like to use this feature?
It would make usage simpler, no need to do same settings multible times.
