proxy says one thing IG says another?

so i bought some static private residential proxies from iproyal i was going to use on instagram and have been running into some issues i hope somebody with more proxy experience might shine some light on. these are US proxies they state are Arizona. now when i plug these into firefox and check ipleaker etc its shows that my ip is in arizona as it supposed to be but when i log into IG it keeps showing me logging in different places such as shanghai,new york,Chicago etc which as you can imagine is not good i already lost two throw away accounts trying to figure this out. iproyal is no help they just keep sending me a screenshot of ipleaker saying "no Arizona", i asked them before buying and they said these would work in IG. what would cause this?

Use 4G mobile proxy

most people use 4g rotating proxies for social media accounts.

I'd recommend you to invest in a 4G Elite proxy(mobile proxy at that). You can search in the market place since many US-based proxies are listed there or start a "Want to Buy" thread.

Send me the ip address by pm, and I'll reply here the origin of the proxy.

That's because you purchased a low tier proxy. Get a 4G mobile proxy: https://www.blackhatworld.com/forums/proxies-for-sale.112/

In general, it means, your software and Instagram use different databases (or algorithms) to detect IP address Geo-location.
More details here.

Different services define IP addresses in different way, also databases can be not actual. Test other services to determine the location, which will show the same geo more often - those show more quickly and more correctly.

By the way, why did you choose Resident Proxies?
