There may be several reasons why Doudian shows that it does not have e-commerce live streaming permissions.

First, it may be because the Doudian account has not completed the relevant authentication process, such as real-name authentication, corporate authentication, etc.

Second, it may be because the permissions of the Doudian account have been restricted or temporarily frozen, which may be due to violations or other reasons.

Finally, it may be due to system problems or updates on the Doudian platform that some accounts are temporarily unable to use the e-commerce live streaming function. It is recommended to contact Doudian customer service or the platform support team to understand the specific reasons and seek solutions.
