Is there any limits on multisite?

I have this plugin installed in a network, with the option that allows me to manage the properties in a central location within the network dashboard.

All was going well up until a certain point, where new website doesn’t get listed so that I can assign a Analytics profile. I believe it stopped adding website when I reached the 100th website within this network. Is there any limit for this?

thanks.
