Meta Suspended IG Accounts for 2 of my Clients

I am in desperate need of help. Two of my clients who are in the pharmaceutical industry have just had their account suspended within 24 hours. Both of these businesses are running ads on Facebook and Instagram. This is completely unexpected. I don’t know what triggered these account suspensions and all Meta has been able to tell me is that the accounts violated Mays community standards we’ve been running these pages for at least over a year and nothing has ever come up in the past I don’t know what’s going on. This is super frustrating and I’m not getting any helpful responses from anyone. Does anyone know what is going on and why are my accounts getting suspended? They are two completely separate clients with completely separate businesses, but both are in pharmaceuticals.
