Brain Visualizer does not show spikes


Hello Everyone!

I’ve just noticed, that using Online platform in all of my projects, including freshly cloned template projects, Brain Visualizer does not show any spikes, it only shows neurons.
Spikes are correctly displayed in the Spiketrain.

I have monitoring TF ready, I am aware of Spike Constrast slider and I am almost absolutely sure, everything was working about a month or so ago.
I’ve tested chrome/safari/firefox.

Does anyone else have this problem?,
or am I the only one with problem on my end…
