I added the Git Integration app by GitKraken and am on a trial period. Thinking we weren't going to use it, I cancelled the subscription. Upon further thought, we'd like to reinstate the app and continue with the subscription.
Given that there is no direct way to do that, I was offered instructions on how to switch our plan from premium to standard and back to premium to reset all subscriptions. However those instructions I think probably aren't updated for the new navigation and I was unable to follow them.
