@banjothreeie87 What platform are you on? iOS, Android, MacOS? It should automatically restore your previous purchase, but if not, Restore Purchase button should do the trick.
Although @friendlyapps hasn't tweeted in a few years, “Friendly for Twitter” is working great for me, so I just purchased a license.
Mac users deserve a good native application, and this is the best one I found.
@JaySan25 Are you set to see “Most Recent” posts? Facebook has been having issues with that feed for the past few days. It seems to have resolved itself for my account now.
