[Bug]: No IOS notifications after rollback into re-release ( 2.14 > 3.0.2 > 2.14 > 3.0.4 )

What happened?

Okay, this one is a bit of a roadtrip, so please stay with me.

we've recently released a version of our app using OneSignal 3.0.4 and we are seeing a marked decreased in click rate of verified delivered notifications for ios only. android looks good. We couldn't find any issue in our QA, nor did we see any increase in crash reports or client complaints. But looking deeper into the data we saw a correlation with the decrease in clicks to a decrease of bonus collection (given by push notifications), also analysing that data showed users that tended to collect said bonuses have stopped taking them entirely after the 3.0.4 release, so the bug was real, we just couldn't reproduce it, until today.

a few months ago we released a version going from 2.14 > 3.0.2 there were issues there so we quickly rolled back to 2.14. The users who got the rollback version AND the new one are the ones who aren't getting the pushes. We manually did this on a QA device and recreated the error. installing a version with 3.0.2 then rolling back to 2.14 and then to 3.0.4 'locks' the device for said app. No notifications are received, not even after removing the app, rebooting the device and reinstalling the app.

Connecting a console log to the device while sending notifications now gives the following messages that appear relevant:

**Received incoming push notification for topic: but for a completely unknown token

incoming message is for proxy client that is *not* connected. baseToken destToken publicTokens ** ### Steps to reproduce? ```Markdown ON iOS 1. build your app with sdk 3.0.2 unity 2020 - install and run 2. build you app with sdk 2.14 unity 2019 - install and run 2. build your app with skd 3.0.4 unity 2020 - update to this version from 2.14 version and run no notifications displayed for said app (status is delivered) ``` ### What did you expect to happen? I expected the notifications to be displayed ### Unity version 2020.3.40 (latest) 2019.4.28 ( for the 2.14 version) ### OneSignal Unity SDK version 3.0.4 3.0.2 2.14 ### Platform iOS ### Relevant log output ```Shell default 16:13:13.511054+0200 apsd incoming message is for proxy client that is *not* connected. baseToken destToken publicTokens default 16:13:13.511861+0200 apsd timestampForTopic? token default 16:13:13.511953+0200 apsd isAppSpecificTokenValid sandbox.push.apple.com default 16:13:13.519455+0200 apsd isAppSpecificTokenValid? found cached token NO error 16:13:13.519656+0200 apsd Received incoming push notification for topic: but for a completely unknown token default 16:13:13.519781+0200 apsd APSPowerLog: {event: , dict: } default 16:13:13.519973+0200 apsd : Sending acknowledgement message with response 2 and messageId (971873555) default 16:13:13.521687+0200 apsd isLTEWithCDRX?

Hey, thanks for reporting your issue.

Are you switching between sandbox and production environments? If so, could you try deleting the app before switching environments?

Unfortunately, I was unable to reproduce your issue on my device. Could you provide a sample repo that produces this issue? Thanks
