Blogging Reminders are not received until the following week

Expected behavior

After setting a Blogging Reminder to a time a few minutes in the future, I expect to get a reminder after those few minutes have elapsed.

Actual behavior

I don't get a reminder after five minutes.

Steps to reproduce the behavior

1. Open the app to manage a site
2. (For easier testing) ensure the site timezone is set to your local timezone
3. Go to My Site tab → Menu tab → Blogging Reminders
4. Schedule a blogging reminder for the current day, a few minutes in the future
5. Wait five minutes
6. Check the system-wide notification screen and notice no notification was received

Tested on Samsung Galaxy S10, Android 12, WPAndroid 19.8

Additional context

• Blogging Reminders on Android was implemented so that the reminder will arrive on the chosen day, but on the following week. Here are some examples: on the selected days, but excluding today.
  • If all days are selected, it will fire everyday from tomorrow onward.
  • If today is Wednesday and only Friday is selected, it won't fire the-day-after-tomorrow but instead on Friday of next week it will fire Friday.
  • If today is Wednesday and Wednesday is selected – and the time of day selected is after the current time – it will fire next Wednesday, not this Wednesday.
• Blogging Reminders on iOS behaves differently (as I would expect); the notification is sent for any reminder scheduled in the future.
• @ravishanker shared that Java's TemporalAdjuster.next is used to calculate the days to fire the notification. This is the relevant file of the app code that uses TemporalAdjuster.next.
• One possible solution might be to swap .next with .nextOrSame, which includes the current day.

Start with WordPress/src/main/java/org/wordpress/android/workers/reminder/ReminderConfig.kt and inspect how TemporalAdjuster.next calculates reminder days. Verify the behavior against the reproduction steps and the selected-day examples. Done means a reminder scheduled a few minutes ahead can fire today, while future selected days continue to be scheduled correctly.
