Remove ".mlapp file has been modified outside of App Designer" prompt

Does anyone know how to stop this prompt from showing up completely? It pops up dozens of times a day, pretty much whenever I click away from my AppDesigner file. I am the only one working on this file and I don't use an external SSD, OneDrive, Matlab Online, a coorporate account or anything like that, so this prompt shouldn't even exist in the first place. If I click Yes, it reloads the file to the point of my previous save, so I lose some progress I worked on and it also takes a long while to load. If I click No, it lets me continue my work, I just have to save the file again, so I always choose this option. This prompt is very annoying, so I will gladly thank anyone who knows how to get rid of it.

As Cris mentioned above, your best bet to address this issue is by contacting tech support. It would be helpful to include the following information:
- Clarify this important part: > pretty much whenever I click away from my AppDesigner file. Does the issue only happen when the app is "dirty", meaning when there have been changes that are indicated by a "*" at the end of the file name in the tab in appdesigner?
- Is the app stored in a version control system such as SVN?
- Does the app use a custom thumbnail image which would be selected in the "App Details" dialog?
I don't expect questions #2 or #3 to be issues in the 24b release (thank you for noting the release) but that info may expedite the troubleshooting process.
