Being in Senegal is the reason the podcast option is missing. Even though you have supported languages chosen you may miss features due to being in an unsupported region like the podcast option.
I do hope all the features for Nest will be globally supported. In the meantime, changing the device and phone languages is a workaround that can get some of the features to work but some will not.
Thanks for posting here in the community-
Huge shoutout to JillG for the help here. It looks like we have come to a solution so I'm going to be locking this thread. If you have any other concerns or questions, please feel free to create a new thread.
Have a great day.
