When started to test the app on different browsers, i pointed my attention to the absence of a main image in the app.
Some times image or not appears (but the results are displayed), or appears but afterward disappears unexpectedly.
It is difficult to reproduce such a state, but when i use a virtual machine (https://crossbrowsertesting.com/) which performance is to slow, i see this state pretty much.
