I've posted before on this and have not received any viable answer. so, i'll try again...I have the desk top app 'windows central' on my pc windows 10. I can start a post but I can not reply to my post. the reply icon remains dark, i can not click on it to reply. could some one please help. the only way I can reply is by going online and signing in to windows central. any ideas would be gratefully received. thank you, Drew.
