I installed the calendar community plugin (first one that shows if you just type “calendar” in the search bar) on my windows PC, and turned plugin syncing on. Then I opened obsidian on my android phone, turned syncing on, restarted, and it asked me if I trusted the vault author (yes), and I see the plugin in settings so I know it’s installed. However, when I go into either the left side bar or the hamburger menu in the lower right, there is no button for opening the calendar like I see on my PC.
In case it matters: on the PC I moved the calendar icon from the right sidebar to the left…
