Hi,
请问您这边申请的邮箱账号是什么?如若MyTI Company Account 已经注册成功烦请查看以下链接提交TI Store API Suite request.
可能是你的账户没有设置成admin role, 可以参考以下步骤在mange user 界面更改成Administrator role.
The user to whom you are assigning the administrator role will receive an email with the subject line, “You are now the administrator of a myTI company account.” To accept the invitation, they must click the button in that email to accept the terms and conditions within 14 days.
