Hi, I posted about this in the forums and seems like more than me are seeing the same issu. The new button slicer keeps resetting to the left most button even though it is saved in another sta...
I'm experiencing the same issue. It seems it has to do with changing any settings in the Title. If I change the Title font, or disable the Title, then the slicer stops retaining its preset value when publishing to the service.
To fix the issue, I click the "Reset to default" button in the Title category and then publish to the service again. The one consolation is that you can at least change the colour of the font without breaking the slicer.
If you follow the steps above and it still doesn't appear to be working in the service, you may need to click the "Reset to default view" button in the service.
