When using multiple clip planes in either the mobile app or the web app there is an issue where in the mobile app if you cross over the clip planes you can end up hiding both the clipplane handles and as a result you lose the location of the "scissors". This means that the model then has to be reloaded. When attempting this in the web app it appears that creating a second clip plane means it actually works in a mirrored fashion. i.e when I try to slide the clip plane from right to left it actually moves from left to right. This makes the clip planes un-useable in the mobile app and web app. No issue with it in the desktop app.
