I have tried many methods including client.focus() clients.openWindow() client.postMessage() message event listening Delayed message queue (to let the client being opened) preventDefault() in notificationclick event Activation event.waitUntil() The situation is that when the device install the pwa twice, the second pwa works normally. However, it is nonsense to ask users install the pwa twice. Is it a bug in Webkit and will it be fixed in the future? is there a workable example? Background: using web-push, iOS 17/18 Thanks a lot 2075845 1 webkit-bug-importer 2024-11-18 08:58:14 -0800 <rdar://problem/140125494>
