Hey @Duijv023,
There's an issue at the moment that Engineering are aware of whereby the Roaming Analytics tab is not showing data/events, it's currently being reviewed. I would recommend opening a case with Support so we can properly track affected customers and Support can provide updates as to when it's been resolved.
I'll try to remember to bump this thread too when it's been resolved, but can't promise I'll be lightning fast!
Cheers,
Connor
