I am trying to use: pushpad
But when the user clicks on the "push notifications" link
It opens: https://pushpad.xyz/projects/3247/subscription/edit?uid=1&uid_signature=b537f55122d37236296c221342b552de26478d36
And the page says:
The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved.
If the project ID is correct, then it's because you're using the link for Pushpad Express, but your project and sender are configured to use Pushpad Pro. You can check that by going to the sender settings.
You need to do one of the following:
my-project.pushpad.xyz
) and create a new project associated to it; finally you can use the link for Pushpad Express
