Hello, I began to use Multisites (Subdirectories) but since that time no pushes are sent nor the scheduled or the ones triggered by other events like before.
I have tried in network site today (using Firebase), push notifications are working fine as expected.
If you are using onesignal, please make sure onesignal plugin along with this plugin network activated.
Go to respective sub-site then go to plugin menu of sub-site, go to plugin settings of this plugin to make sure required settings are set as well as in onesignal plugin
I have attached below screenshot showing push notification from network site for your reference (using Firebase).
Please make sure correct service worker file is registered in browser -> more tools -> dev tools -> application tab – service worker . If you are firebase then service worker from this plugin needs to be in active status otherwise if you enabled onesignal, it should have onesignal service worker file from onesignal plugin
if you see below, service worker file from this plugin for Firebase push notification is registered and active pnfpb_icpush_pwa_sw.js , similarly if you enabled onesignal option then it needs to have onesignal service worker file.
I found the exact problem, problem occurring from second sub-site onwards(in WP network sites), I will fix this problem and next release will be in few days. Thanks.
