Before you make comments please remember you are replying to me and I Used Samsung devices for past 13 years and I used each and every USA CANADA model as part of my job and submitted weekly reports on bugs and issues. so trouble shooting Samsung devices is not new to me.
Also remember this issue is NOT reproducible on Main whatsapp application only happens on Dual messenger
Problems are still there no solution found at.
