Why are there no posts in the local feed?
The location feed is cleared every 24 hours. Therefore any post that has been made in your area (within your location area you have set) will only stay visible for 24 hours. This way you, as a user only sees new posts and not irrelevant or old posts.
Another reason may be because there are not enough users within your set area, remember AppZaloot is a brand new app!. Try expanding your radius to include a larger area.
If there is still no posts, perhaps you can use your invite link to invite your friends to the AppZaloot community and start the conversation.
