Shaikh IzajAhmed,
When does this issue arise exactly? On which button are you clicking to see the wait message? There is the Publish box in which "Article is ready to publish" is auto-selected. So if your article is ready to publish, you have to simply click on the button below that, 'Save article'. The article will then get submitted.
Note- Kindly do not use short forms of words like TIA. This is not a social media platform and we encourage members to improve their English and writing skills by using words in their complete form.
