[Samsung Galaxy Z Fold 4] FordoGMan:
Hello all - I apologize in advance if this may not be the correct way to approach my issue; whether that be post locale, or otherwise..

So.. Not long ago (4-5 months ago) I went to ATT to transfer my S21U to someone else on my plan, and upgrade to the Z-Fold 4; I did the whole "Smart Switch" rigamarole, and all seemed to go over smoothly. After about 3-4 weeks into using my Fold4, I realized that I wasn't getting notifications as promptly, or regularly as I used to. In fact, I was getting what I have aptly named "Ghost" notifications.

What I mean by that is I would get the usual notification sound, but nothing to show for it. No evidence of any app having new data pushed to my phone whatsoever. I did quite a bit of research.. looked into the Notification History, checked each apps Notification permissions/settings.. nothing was off/out of the ordinary. Eventually, after not finding *any* sign of how to fix this.. I turned off reminders, as I would get constant notification sounds without any idea as to which app was prompting me. The biggest contender to this issue is Snapchat. I've quadruple checked in-app settings, and sextuple checked phone settings - everything is cranked to the max to make sure the notifications reach me visually, and audibly.

There are some other apps that I believe have the same issue, or a similar but less regular issue. GMail app will send me notifications as you'd expect.. but I will get 10-20 email notifications all at once, instead of seeing them come in 1s or 2s like I had before on my S21U; not to mention I can no longer get the "Is this You?" login notification from GMail when signing into a new/forgotten device.. Same for say Steam/Steam Chat apps.. I don't get many notifications from those, but I don't see them at all, anymore. The Messages app is the only consistent/normal behavior I have as far as I can tell. Among some more background oriented notifications like State Farm's "Drive Safe & Save", and system apps like Modes and Routines etc etc..

So, my question is.. ultimately, how do I fix this?! Is there maybe a file that was brought over from the S21U that might be causing conflict? Some kind of system cached files preventing the apps from sending the data down the right 'pipeline' so to speak? I've tried forum after forum in researching this.. I could not find an answer. I'm finally Fed. Up. I don't want to have to completely wipe/reset my phone as I've a lot of apps, and data that I would very much like to not have to back-up, or set up again. It takes me hours.

I was using the Nova (prime) Launcher for quite some time.. and did Smart Switch while it was active on the S21U; but decided to switch back to OneUI once the newest update came out.. ((really like the quick-access toolbar when unfolded - which doesn't work with launchers)) .. Could the launcher have caused some weird rare issue?

I'm at a loss here. I've no clue where to go; I've been on Windows systems my entire life, other than the slightly more advanced use of Android in between. To finish off the info, all apps are up to date.. Android OS is up to date.. as far as I can tell, I'm never more than ~5-10% behind on updates when I check based on the amount of apps, and data I have on my phone.

Help. Please. Lol

Thanks, ahead of time. Will check back every couple hours to see what questions/answers might come along.

Regards,
