when your user login, save his push notification use id to a data base and for sending notification get his id,
for example, you set data base in airtable,
Name mobile User id
imran 0345xxx sdc343d
you have to get that user id to send specific notification,
Note: for every login you must have store user id, because on login it changes user id, if user delete app and install again then user id will be changed
I haven’t done the test yet, but I was asked not to test at the compenion. You need to install the apk and place the block on a timer with at least 5 seconds. I hope that right.
