Instagram claims that the process of reviewing and responding to an appeal for a banned account usually takes up to 24 hours. However, it is important to note that this process can take much longer in some cases. If your appeal is not accepted, there may not be any further options available other than downloading your data. In this case, your disabled account will eventually be deleted by Instagram. Keep in mind that the decision of Instagram is final and you will not be able to regain access to the account.
