Modal issues on iOS 13 - note for developers

Guys you need to change for all modal viewcontrollers the presentation style to fullscreen! The default value has changed in iOS 13. To reproduce issue use slack on iOS 13 and try open some image preview from messages, you will see how buggy it is ;)

Looking forward for update!

I Beg you for little improvements

App is awsome but:

Can you please add some tiled (/chockolate/?) View for pics which are in some workspace? With visual differentiation-if pics were comented or were signed as good(/liked) than they should be bigger, to be able to localize them quickly?

Time line is ok, but sometimes you need to see only pictures one by one next to eachother... Like on pinterest, googlekeep and so one. It would be really nice to have this option. Your system is so advanced and well prepared that it shouldn't a be big deal for you.

Also for our comfort, it would be nice to be able to personalize a little colors of slack, for example, to be able to change color options (but pleace not fitted as you have them in slacks icons, it's not in my taste :p) and to "pin" them to different workspaces. To make them not as similar.

There is logo always up, your logo... And it would be GREAT to have there my icon of workspace instead. It would help much to not mix different plots together...

Last thing, it would be great to be able to add to channels pinterest and dropbox link, so we would be able to open this link in your app, to have it always "under our arms"/on the top... Or if its not possible, than just to be able add there a hyperlink that every member can use. The same way that its with another channels.

:D can you do this for me? I can send you a chockolate if you will give me adress. Look! You have 5 stars from me already! But i want to give you 10 ;-)

This app is buggy af

To be honest, never saw notification from Slack. Ever. I am sure I have them turned on for Slack on my iPhone.
But today is the best. I open up slack. No refreshing. I kill app. Open up again. Nothing. I pull up to refresh, got “all is fine and updated” or something like that. I can see that nobody is marked as active, even me and I’m sure there are people active on this slack group.
I go further. Open Control Panel, turn off both 3G and WiFi. Open up slack. “Everything is fine”. Kill app, restart. “Everything is fine”. Yeah. You know that meme, dog sitting in the middle of burning room saying “everything is fine”? Slack is that dog.

Yikes, that sounds terrible. If you're willing to send us a note at, we'll be more than happy to see how we can help with this. Thank you so much for your patience!
