If it’s like a DDoS attack, this is a little trash, but you can contact Bubble, wait for their support team, then wait for someone in engineering to enable DDOS mode, then same thing to have it disabled. @aless helped me with this and I don’t think they have automatic detection yet for DDOS attacks.
Server logs? Or users editing Bubble logs? There are server logs for you app, but I don’t believe any logs that log users editing in Bubble.
