Urgent! About "Provisioning Profile" request

We are the developer team of Nanjing Qinheng Microelectronics Co., Ltd. Recently, we have carried out device driver development and system adaptation for a variety of USB-to-serial chips. At present, our project is stagnant in the release stage because the "Provisioning Profile" does not contain our vendor ID(0x1A86). The release process of this driver will affect millions of users worldwide. We hope that the "Provisioning Profile" can be completed more quickly. This is very important for our customer and the experience of Apple's Big Sur.
