Ok…if anyone having issues while creating means there is some common thing leaking while creation this may help you.
Well, Appcloner is not gonna work to the perfect. Also re-cloning always gonna take lot of time.
Here are the things you should consider changing before you create account.
IMEI
Android ID
Advertising ID
Device ID
GSF(Google Service Framework)
Harware Serial
Bluetooth&wifi Mac Address
Wifi ssid
Mobile Number(not necessarily)
Sim Card Serial
Sim Subscriber ID
Sim Operator
Build Fingerprints
Make sure you change all these details before you create another account. And make sure u just resintall Official IG app for every account (after changing the above details)
AppCloner cant change lot of the above details, and the cloning process takes lot of time.
You can use xposed to achive all the above things.
Main thing, change your mobile brand and android version details too. It makes the mobile entire new.
If you can able to do all the things above mentioned you are good to go and no linking between accounts. You can purchase various network sims and change them here and there and roam for tower switching make more quality.
Cheers.
EDIT: Make sure you dont have any gmail attached to playstore.
