A simple fix will do the trick — delete "ZilSwap" under Zilpay's "Connections", disconnect your ZilPay wallet on ZilSwap, and reconnect.
Rewards are distributed weekly. To claim your rewards, you will first need to connect your ZilPay wallet and hit the "Claim Rewards" button. The amount of ZWAPs you are elligble to claim for that week will be listed under "Unclaimed Rewards".
If you do not see your ZWAP being credited to your ZilPay wallet, please allow for the transaction to process for a minute before refreshing the page.
Every epoch's reward claim is a separate transaction (one reward distribution per week, every Wednesday). If you have multiple claims to make, claim your first reward, hit refresh, and click on the ZWAP window again to claim your next epoch's reward.
Click on the "Unlock Wallet" button on the top-right corner of the ZilSwap page. You will be prompted to type in your password to connect to ZilSwap. Once you're done, hit "connect" to approve the connection and you're done!
