Thank you for recommending the avec Bonus app. There may be various reasons why the recommendation is not possible at the time: 1) The recipient is already registered as a customer. 2) The app has already been recommended to the recipient. Recipients cannot be referred by other members for one month after receiving a referral. During the same period, registrations are assigned to a recommendation and rewarded. Last but not least, technical difficulties can also prevent the sending of a recommendation.
