My Media Pro Gallery was working flawlessly until I updated to Adobe's new build 2017.1.0.821. With this build what happens is centrally pinned items below the gallery canvas shift to the left. This just happens before the footer item - everything in the footer is aligned properly - Everything above the Media pro Gallery is aligned great to - just the items below between the gallery to the point where the footer starts. If an item were to be places on a free page within the site and it is centrally pinned it works right so I know its a conflict with the showcase widget and this muse build. I am also separately testing Adobe Muse's pre-release build 2017.1.1.15 - this version even makes the situation worse - what happens now is that the Footer contents shifts vertically up and covers the gallery images. as shown in the last pic. So essentially, all this is leading me to believe any potential release from Muse as way of updates on the official download feature is going to have further problems. I am more than happy to provide the muse-themes file with a testing site to see what I mean. If there are any fixes for this let me know. The way the site flows is I definitely want the content below this Show canvas area and compromising on that would just throw out all the design thoughts put into the site.
