Delay notifications issues after the October update

[UdoyPaul]

Device: S20 FE 5G Indian Snapdragon variant.

I"m facing delay notificationd issues after the October update. Before I didn't face delay notifications issues. Improve the battery backup now. But I need Early/instant notifications in Gmail, Messenger, WhatsApp, etc. I receive the notifications 5-120 minutes later. How can I fix it? 

Thank you.

Thanks for your kind information. I called the Samsung support center. They told me, can't possible to go back previous software security patch. How I can hard reset or get the previous software versions?
Thanks,
Udoy Paul

Ok if its under warranty u can try some good youtuber tutorial video search ur problem on youtube and diy but.... If it out of warranty and u messed it up someway it will be expensive for u to get it fixed from samsung now, so better do to samsung service center try convincing them be polite , they will roll back it for u, but before roll backup try reinstalling the latest software from scratch from service center 99% this will fix ur issue, else go for roll back use social media to gather evidence whether latest software update is actually breaking and causing the issue u facing. It totally depends whether they want to do it or not, samsung online support will give you copy paste answers from there poilcy
