I'm having this issue with the horizontal gallery control wherein the navigation buttons don't work unless I move to the second item first using the scrollbar. Once the second item is selected, then the buttons start working.
Has anyone else encountered this? Is there a fix for it?
Thanks @Anonymous but are you able to replicate the issue based on the steps I've provided?
Running it while in the editor will not exhibit the issue. It needs to be run as a published app - Play the app don't Edit it.
I am also having the same issue.
I have a horizontal gallery. The gallery "card" takes up all the space on the screen, so only 1 item is showed at a time. Scrollbar is disabled, Show Navigation option is enabled. On the first item the first time, the nav buttons don't work. If I then "scroll" with my keyboard arrows and the second item is displayed (even just a little bit), then the nav buttons start to work.
I had the same issue. My navigation controls would not work until I scrolled to the second item, after which they would work as normal. However they would only work for a few clicks, and then would mysteriously stop working.
I was able to fix the issue by changing the Navigation Step option to 2 instead of 1. Strangely, you would expect the navigation buttons to jump two items at a time, but it seems to be random, sometimes navigating by one item and sometimes by two.
Not a perfect solution, but maybe it can help you.
I'm having the same issue - horizontal gallery navigation works when editing the app in PowerApps. When you embed it in a SharePoint site - it fails.
If you can even supply a best practice solution for moving between records using manual buttons that would be great.
