I haven't been awarded my Bloom Day badge!
Firstly make sure that you have the following things covered:
Have you added a milestone with a date of the 15th of the current month?
Is the milestone marked as either ‘Blooming’ or Flowering?
Have you added a photo to the milestone?
Note: You’ll need to log the bloom in the same month as when it occurred for the badge to be awarded, so you have from the 15th of the month to the last day of that month to log your milestone and be eligible for the award.
