After the Android 10 update on the Galaxy S10 notifications have been either delayed or non existent. Battery optimization is turned off as well as do not disturb and it still happens. I also tried doing a factory reset and setting everything up again and the issue is still occuring.
I found the same results . Uninstalling and reinstalling an app gets it working for a short period but then it goes back. The same was for when I did a factory reset on the phone. Gmail seems to be the most affected by this issue.
Thank you all for reaching out! I am looking into this further. @trailblazer15 your information is very helpful! As soon as I find out more information. I will follow back up with you here.
Same here, the delays are so bad it's like 1 day behind sometimes, so I would get a Facebook or an Instagram or a whatsapp notification 1 day after! And when I open a Nest notification it eod do nothing but then a day later Nest just pops up to that notification I clicked 1 day ago!!
Yeah it is bad, I keep missing notifications because they are either super delayed (can be days) or they don't come at all. The issue still exists in the January 1, 2020 update.
@trailblazer15 I am still working on this for you. Is this still occurring on all apps or just specific ones? Just to confirm, this is on Wi-Fi and Mobile Data? Have you already spoken with your carrier? Have you re-seated the SIM card?
