profile not change issues

@shamsul_0765 The message: "The Acrobat Sign account for alam@akhknit.com is associated with a different profile. Switch to your DEL-BlackZone profile." indicates a User ID conflict within the Adobe Enterprise/Teams structure. Since this is an enterprise/account management issue, it cannot be fixed within your Adobe Acrobat application settings. You need assistance from the administrator of the "DEL-BlackZone" account.  Ask the IT administrator or person who manages your company's Adobe licenses (the one responsible for the "DEL-BlackZone" profile). Ask them to remove your email address (alam@akhknit.com) from the "DEL-BlackZone" User Group or Organization structure in the Adobe Admin Console. Once your email is released from that enterprise profile, the Adobe system will stop forcing the redirection, and you will be able to log in normally under your standard or individual account.
