Troubleshooting
A robot that won't connect is usually a driver or permissions issue rather than a RobotMagic problem — confirm the connection is recognized by your computer or phone outside RobotMagic first, then refresh the simulator tab, since most connection prompts are waiting on a browser permission that's easy to miss.
A stuck simulator most often clears with a hard refresh (not just navigating back) — the simulator runs in an isolated tab context, and a stale state occasionally needs a full reload rather than an in-app retry.
A login error is most commonly an expired session on a shared or classroom device — sign out fully and back in rather than just reloading. If a student's account specifically won't log in while others on the same device work fine, check for a duplicate account before assuming it's a technical fault.
