Once you have accepted an exchange proposal on Sticker Master, you will need to complete the exchange directly on Coin Master to make it effective:
• Click on the green button on the proposal screen “Add friend on Coin Master”. This will add the user to your Coin Master friends list.
• Open Coin Master, select the card you want to send, and click on the “send” button. Choose the user you just added from the friends list, then the cards to send based on the proposal.
• After sending your card and verifying that you have received the one from the other user, return to the proposal page on Sticker Master and click on the green button “I sent and received the cards”.
• You can leave positive feedback if everything went well. If something did not go as expected (e.g., the other user did not complete their part of the deal), you can report the user (negative feedback).
Note: As a guideline, the user who made the proposal should send their cards first.
