Is it possible that problems from Old iPhone 6 can be transferred to New IPhone XR???

I have recently just purchased a brand new iPhone XR after having serious problems with my iPhone 6. It would automatically shut down my apps while on them, and some apps would not even open when I tapped on them. My Instagram would not open unless I downloaded it every time, however once I exited the app and tried to go back into it, it would not open.

however, now that I have a BRAND NEW iPhone XR, I am having the EXACT SAME issues and am wondering how I can get rid of this?? I have done absolutely everything that has been suggested including:

-the latest version of Instagram (including bug fixes)

-restarting my phone

-deleting the app and re downloading it

-I have wiped my whole phone

-Updated my back up 3 times from iCloud

-Deleted recent apps (almost all of them) that could be impacting the fact that Instagram doesn’t work

-I have bought more memory

-Factory reset

-Emailed/ messages Instagram numerous times (with no reply)

PLEASE can someone advise me on what to do???

Thanks so so much I’m advance!
