I’m also still seeing this issue. This code produces the above error, Trigger of type: calendar is not supported on Android.:

await Notifications.scheduleNotificationAsync({
    content: { body: 'Hello' },
    trigger: { channelId: 'default', hour: 10, minute: 23, repeats: true },
});

This code does nothing (note the omitted channelId):

await Notifications.scheduleNotificationAsync({
    content: { body: 'Hello' },
    trigger: { hour: 10, minute: 23, repeats: true },
});

Mine is 39. Dunno if there is any minor update. or if the version of expo- notifications matters. Let me check it out tomorrow

Thanks for the advice. My expo-notifications is ~0.7.2 which is the latest for now. I have checked the changelog just now and saw @sjchmiela had already merge a fix to master branch of expo https://github.com/expo/expo/pull/10454. The revised code is not yet available in sdk-39 branch though; so we may still come across this issue. Looks like it will be publish in near future. By considering that, I will close the issue and try wait for update. Thanks mates!
