As when I used fb I thought that fb us the best and the messenger both are best and easiest one to chat and new things to explore but as we can say that with a single thing u can’t survive modification is needed than instagram came initially I didn’t get what is there .slowly I came to know in this only u have to follow another will follow you there is no need to send request and all just approval is needed u can chat also and u can see what other are posting whereas brand u can follow their best deal u can came to know u can also put your dp as you are using in Facebook but it’s easier than fb and messenger it will provide both in a single .so just go for instagram and uninstall all other
