Is there any problem with using one signal?
I can get to the subscribe button, but the message is not sent.
In bubble, the workflow proceeds without error, but in onesignal, no user list is fetched and no message is sent.
Not only new messages, but also messages that were sent properly in the past are not sent.
I’m putting off app lunching because of this issue. very sad.
Somebody please help. 
I use this plugin
