In this article, we'll explore the most common reason people can't post to a group
If you can't post to a group, or the upload limit is showing 0/0, the most common reason is usually that there's a posting limit set.
These limits are usually 1, 3, 5 or unlimited daily or in total. This is per member over the lifetime of the group, including you.
This is set by the groups creator and cannot be changed by contributors, only the groups admin.
For Group creators
You can disable this by going to the group > Click the 3 dots > Scroll down to posting limits > Set your new preferences > Save
