Test instructions

• Install this plugin: https://github.com/Soare-Robert-Daniel/test-black-friday
• Test:
  • If the notice appears during the Black Friday period.
  • If the labels change based on the license status (described in the spreadsheet)
  • If the notice can be dismissed.
  • If the notice appears only if the plugin is 3 days old. Warning: You will see the notice if you have another product that is older than 3 days; in this case, better to disable them.
