Why is there no setting in the upper right corner of the home page?

The reason why there is no setting in the upper right corner of the Buy More homepage is because there is no design setting button in Pinduoduo. The setting method of Buy More food information is as follows:

1. Enter Pinduoduo app and find the function item "Message Receiving Settings".

2. Jump to the message receiving settings and find the item "Notice of preferential activities".

3. Enter the activity notification reminder setting page and open the "Buy more food" option.
