snapchat banned

I’m using a jailbroken phone ios 14 I was wondring factory reset will work? If not is there a tweak to fake device informations to make it work?

so basically i have been promoting on snapchat and all of a sudden whenever i attach a url to a snapchat. it will say "fail to upload to story" any other picture will upload to the story just fine. i made a new account and same thing. then i switched devices thinking my imei was banned. same...
