Getting multiple notification for some apps

[bea003]

This started happening very recently and it's jarring. 

When I make a payment and I get the usual notification from the bank, in 5 or 10 minutes I get the same notification again and again and again. The same thing with WhatsApp, same thing with many apps on my phone. 

It's so annoying and I can't find any recent solutions that work. 

Its a galaxy a23. 

Thank you.
