No, I have not yet taken the time to look into this particular problem, it happens too rarely. I would do tests one of these days. The problem is that to reproduce this bug, you have to connect then disconnect and so on, it's not practical.
For my part, it is the question yes or no on my phone for the validation of Opera on my PC. I touch yes, but the answer does not pass if I disable Adguard in Android and Opera on my pc, the answer passes.
