I'm not sure the value of end to end encryption for proprietary application chats. For emails and SMS messages, your messages are being sent between different multiple servers on the open internet and it opens you up to spying, but end to end encryption on instagram is only protecting your chats from Meta.
I find the end to end encryption on Facebook to be detrimental to ease of use, because you always have to use a pin code, etc for the web interface.
If you don't trust meta with your chats, you probably shouldn't be using their application to begin with.
