Is the instagarm algorithm heavily penalizing multi account management from the same device lately?

Check each account’s status and recommendation eligibility first then compare recent posts for watch time and any changes in content frequency.

maybe try separate browser profiles and check if your accounts have any restrictions first.

Your accounts will be linked by device fingerprint and network information, so if one of your accounts gets flagged, it will affect your other accounts.
It would be better to give each account its own mobile environment with a dedicated proxy to avoid the account-linking issue(as Instagram is a mobile-first platform, a browser environment may also kill the reach)
Test it with one account first to see whether it's a device problem.

Hey everyone, I've been running a few niches pages, but lately, whenever I switch between accounts on the official app, the reach on the secondary accounts flatlines immediately. Are you guys using specific emulators, separate browser sessions, or specific tools to manage multiple accounts safely without hitting hidden flags?

it might also be possible that the secondary pages themsellves are facing issues not related to switching accounts. reach on instagram is very inconsistent.i would first find out if all the posts or just reels have lower reach before going ahead with a new strategy altogether.otherwise it is easy to fix something which is not the problem.

switching accounts in Instagram's own app is a normal feature, so i wouldn't assume that's causing the reach drop. lots of people recommending antidetect browsers and mobile proxies here, but neither guarantees better reach. i'd check if the secondary accounts have any recommendation restrictions first.

It was the same way before, it’s just that the system is now smarter at identification. Consequently, even if you try to use a proxy, having multiple accounts on a single device will still lead to issues this is expected, as the platform wants you to follow the rules.
