What's New in Version 3.34

Bug Fixes
• Tapping the status bar to scroll to the top on an iPhone X was previously jerky and jumpy, which was funky, but not in a good way.
• Fixed: File previewing - particularly full screen - on the iPhone X needed a little fine-tuning. It is closer to fine now.
• Fixed: When viewing posts on an iPhone X, the text from the post was spreading itself about more than was polite, or necessary. It now tucks itself in, as intended.
• Fixed: The app was disrespecting the “Mark as Read Immediately” preference, by not immediately marking as read. Respect was due. Respect now given.
• Fixed: After swiping between a thread and channel there was very occasional sluggishness. No more.
• Fixed: A couple of rare crashes, caused by such things as: A button, no longer visible, attempting to use itself, and random messages somehow imagining themselves to have negative height, therefore creating a kind of mini black hole into which they collapsed. You won’t have seen these problems, because as mentioned, they were either invisible, or occupied theoretical negative space. Regardless, the things that no longer were have ceased to be, leading to a sharp uptick in crashes that no longer happen, and a mild philosophical headache.

Best in class

I love Google chat, but it doesn't allow you to call out an individual in a channel or allow you personalized notification settings. While I may use Google chat for many of my personal conversations, Slack is where I go for team conversations.

That said, from one product manager to another, enhancing navigating between photos could be worlds better. I use the app to send screenshots and not being able to swipe between attachments is painful at best.

Additionally, I've gotten a few black screens that are solved by going to the home screen.

P.S. Whoever is writing your release notes deserves a raise. They are the highlight of my week and I can only hope one day some one reads my release notes with the same enjoyment.

An incredible application for teams serious about communication

I am the CEO of a multidisciplinary healthcare Corporation involving 19 providers and 74 employees. I was the impetus behind on boarding slack and maximizing as well as refining our communication corporate wide.

We have been working with Slack for approximately eight weeks and I can say that I am very happy with how it has optimized our communication. I am looking forward to the additional services that are offered with the paid plan; as we are now using the free plan in a trial phase.

I would highly recommend slack for any business no matter how big or small, which is serious about communication.

I consider my decision to use Slack one of the best administrative decisions I have made. I highly recommend it!

Mostly great, one annoying bug

Slack is mostly great but whenever I sleep the phone with slack active I come back to a black screen that won’t go away until I open task manager and swipe it away. Then I have to re-open it :( Super annoying, but the app would be great if you fixed that one thing!
