Instagram Restricted Access After Closing Facebook

Ever since I closed my Facebook account, my Instagram has been bombarded with "Confirm it's you" alerts, severely limiting my account's functionality. I can't like or comment on posts whatsoever. There's a glaring lack of proper guidance on how to resolve this issue. I've been grappling with this problem for a while now, and I'm desperately seeking assistance from Instagram authorities. It's baffling how my decision to deactivate Facebook has caused such turmoil on my Instagram. I want to enjoy the platform without restrictions. I implore Instagram to step in and help resolve this issue promptly. The frustration is mounting, and it's disheartening to be caught in this digital quagmire with no clear solution in sight.
