Adam Kos You don't have to access Apple's apps and services only through the titles installed on the device. You can find the most important ones on the website. The vast majority of them are integrated into iCloud, the services then have separate pages. You can find their overview here.
iCloud

the website was always more of an emergency, so now I tried again, where it moved (Chromium based browser in Windows)..
1; if a person uses a hashtag in notes, either knowingly in connection with the new functionality in iOS15 or simply because the inserted text contains such a character followed by text, the given note becomes invisible on the web, until the hashtag is deleted
2; some reminder lists sometimes appear empty on the web even though they have x active (unfinished) items on the phone
3; impossibility to set the date, time, let alone notifications based on location in comments on the website
4; when entering an event in the calendar, there is no switch to take travel time into account...
.. so for me it still applies that in an emergency, to write down something urgent, when one would not have a phone or a watch at hand
