According to ChainCatcher, the official support Twitter account of the Worldcoin project (World App Support) posted that during peak blockchain traffic periods, transaction processing may be slowed down due to network congestion.
Due to the high volume of blockchain activity, it may take longer than expected to receive grant funds in your World App account. If you want to keep a close eye on this, you can monitor the wallet address history on Optimism Explorer. Once the transaction is confirmed on the chain, you can see that the transaction record has changed status to "Success".
