Help with Account Issues

I initially signed up for a free trial with my instagram account. When I upgraded to pro, I used my meta business account. I need to merge the two some how.  We are trying to set up an automation and every time I know try to connect my instagram to the pro account, it says it is connected, but it is not. It is the other account.   Is my only option to delete the free account and then re-add instagram under the pro? I cloned everything to the pro account already… does this mean my contacts from instagram that already subscribed are now in the pro account?
