Unfortunately, you can't be rewarded if you don't convert your steps. To receive your Wards, you must click the "Convert my steps" button when you reach a level. You can do it at the end of the day or after your walks, but it must be before midnight.
You can activate a daily notification to remind you to convert your steps. For more details on this subject, please check the following article: Enable/Disable the step reminder notification. 😁 ⏰
From now on, you won't forget to convert your steps and will get your well-deserved Wards! 😜
