OK, so I suppose this thread deserves a more comprehensive post about what I'm seeing.
I had 7.1 and opened my doors in my garage. They open
nearly all the way. In fact they open all the way depending on where I'm parked in the space. I selected the "open fully in this location" option and found that they would open as much as possible without hitting the overhead garage door. My interpretation of "open fully in this location" was more like "try to open fully in this location," in other words, override the "indoor" setting. I find that setting too low because I wind up with a lot of awkwardness with the front door and the corner of the falcon wing door.
So everything worked as expected. When I opened the doors in my garage, there was a section in the dialog that said something like "fully opening location" with the ability to delete by hitting an X. But they always opened more than the indoor setting.
Then, I upgraded to 8.0, and they stopped opening more than the indoor setting. The section that said "fully opening location" was gone. The option to set the location as fully opening, also gone. I have done as
@Aljohn suggested and tried overriding the door opening - effectively opening them further. The "fully open in this location" option doesn't appear.
However, once the doors are truly fully open - not just overridden to some extent, but completely open, the option appears.
In summary - I believe 7.1 allowed "fully open in this location" to be set when overriding the "indoor" mode to any degree. 8.0 requires that you truly open them all the way before the setting appears. Upgrading to 8.0 appears to have removed my existing setting as well. I have not tried to make sure the functionality is the same. That is, I haven't ensured that "open fully in this location" will still use sensors to stop to the doors, but I'm assuming it will. I'll work on that tomorrow and hopefully be back in business.
Hope this helps!
