This issue should be tested in one Android and one iOS device. Test change reminders format Install the previous version of the app (e.g. from the store). Login in a site. Go to calendar, open the top-right context-menu and click "Settings". Change the "Default notification time" to any value except "Disabled". Please remember which value you chose. Create a calendar event in the future (e.g. 4 hours from now). Open the event and add a couple of reminders. Please remember the times you used. Now install the new version of the app (with this patch applied). Go to calendar, open the top-right context-menu and click "Settings". Check that the default time is the same you set before. Open the event. Check that the reminders are the same you set before, but now they use the "time before" format. E.g. if the event time is at 18:00 and you set the reminder at 17:00, now the reminder should say "1 hour before". Add a new reminder to be triggered "soon". Wait until that time comes and check that a notification is displayed at the right time. Test add reminders when creating an event In the app, click to create an event. Check that you see a "Reminders" section in the form. Create the event, setting a couple of reminders. Open the event. Check that you can see the reminders you set in the creation form. Open the top-right menu and click "Edit". Check that you don't see the "Reminders" section (for now I've only added it when creating the event). Now repeat steps 1-3 but being offline. Go online and synchronize the data. After synchronizing, open the "offline" event again and check that you still see the same reminders.
