Hi! I understand that your Proton Calendar app on Android isn't updating the times after you've traveled across different time zones. Let’s see if we can get that sorted out for you.

First, a quick check: Proton Calendar currently doesn't let you manually change the time zone inside the app itself on Android. Instead, it relies on your device's time zone settings to adjust events accordingly. So, if your calendar isn’t reflecting the correct times after traveling, the issue might be with how your phone’s time zone is set or synced.

Could you please check these and let me know?

1. On your Android device (WebKit on Android 10), go to Settings > Date & time.
2. Make sure Automatic date & time and Automatic time zone are enabled. This ensures your phone updates to the correct local time zone.
3. Restart the Proton Calendar app or your phone to refresh the settings.
4. Open Proton Calendar and see if event times are now correct.

If those are already set and the problem persists, sometimes Proton Calendar events will keep the time zone they were created with, and they won't auto-adjust to new time zones. For events, you can:

- When creating or editing an event on Proton Calendar (web version or app), use the Show time zones option to specify an event’s time zone explicitly.

Last but not least, please ensure your Proton Calendar app is updated to the latest version from Google Play, as updates often fix bugs related to syncing and time zone handling.

Let me know if you’ve already tried these or if the issue remains, and then we can dig deeper!

The part about keeping new time zone and resetting worked. Thanks

Glad to hear that setting and resetting the time zone helped! Regarding your question about the Proton Calendar app keeping new time zone settings, here's what I can share:

Currently, Proton Calendar on Android does not allow changing or keeping a specific time zone directly within the app settings. Instead, it relies on your device's system time zone to show event times. This means if you travel, the calendar adjusts events based on your phone's local time zone automatically but does not remember or lock a custom time zone setting inside the app itself.

This limitation has been noted by users and Proton is aware of it—they have an existing feature request to allow manual time zone settings inside the app, but it is not implemented yet. As a workaround, you can access your Proton Calendar through a web browser at calendar.proton.me and set event-specific time zones there under event settings by using "Show time zones" when creating or editing an event.

Here are the key points for you:
- Proton Calendar app on Android takes the time zone from your device.
- No built-in feature to manually keep or lock a time zone in the app yet.
- Web app (calendar.proton.me) lets you set time zones for individual events.
- Proton's development team is aware and may prioritize adding this feature in the future1 2.

If you frequently travel between time zones, managing events through the web app might give you tighter control over event times.

Does this help clarify the current behavior? Would you like guidance on using the web version to manage event time zones?
