Presenter couldn't load because resources were blocked by your network. This usually happens when a corporate firewall, proxy, or content filter prevents them from downloading.
Troubleshooting
Try connecting from a different network (e.g. personal hotspot) to confirm it's a network issue.
Ask your IT team to allow this application's domain in the firewall or proxy.
Disable any browser extensions (ad blockers, privacy tools) that may block scripts.
