When using Connect, I don’t see all of the comments. I was just looking at a post where the counter showed over 40 comments, but I counted them and only saw about 16. Then I opened up the same post in my web browser and I was able to see all of the comments there.
You can update by going to the app store. Clicking on your profile picture. Then click manage apps. You should now see an option to update all your apps.
You can also wait and it will be updated for you. I’m not sure when that will happen.
The problem is I never know the app even has an update. I don’t frequent the play store ever.
