Instead, it displays the tagline 'Only some people can post.' at the bottom, where I would normally enter a message (below left). It's not a simple permissions problem'I'm the administrator of the workspaces and the owner of the channels in question. The first time it happened, I just switched to my Mac to post. For another day or two, I didn't need to post anything to Slack from my iPhone, but the next time I did, the restriction annoyed me enough that I force-quit Slack in irritation (below right). To my relief, that simple action solved the issue because I had no other ideas about how to regain the posting privileges a user of my level should enjoy. Nevertheless, I attributed the problem to cosmic rays and moved on with my life. A few days later, however, Glenn Fleishman said he had run into the same issue, and the next day, the problem recurred on my iPhone. Clearly, the problem wasn't just a one-off occurrence on my iPhone. If you run into the problem, force-quit Slack by swiping up on it in the App Switcher. Remember, force-quitting iPhone and iPad apps is helpful only for resetting badly behaved or frozen apps'it uses more memory and battery power than letting iOS manage the apps automatically (see '[1]Why You Shouldn't Make a Habit of Force-Quitting iOS Apps or Restarting iOS Devices,' 21 May 2020).
