Troubleshooting
Troubleshoot common problems
Work through the most likely causes when joining, responses, prompts, polls, or displays are not behaving as expected.

My students cannot join
The usual cause is a mismatched code or closed participant access.
- Confirm the hosted-space code and session code from the same dashboard.
- Turn on Accepting responses.
- Ask the participant to return to
/joinor scan a newly opened QR popout.
If only one device is affected, try another browser or network on that device.
The QR code opens the wrong session
Close the projected QR window and select QR popout from the intended session dashboard. Do not reuse a QR window left open from an earlier activity.
Students can submit, but I cannot see responses
The responses are usually screened, hidden by a filter, or arriving in a different session.
- Open Room controls and choose All prompts and All time.
- Check whether Screen submissions is on and review hidden cards.
- Select Refresh responses.
- Compare the participant’s two codes with the host dashboard.
An image will not upload
Confirm Image uploads is enabled under Participant inputs. Try a PNG, JPEG, WebP, HEIC, or HEIF file no larger than 10 MiB. If the image option is missing for everyone, private uploads may not be configured on this deployment.
My prompt has not changed
Select Show after editing and look for the saved status. A question loaded from the bank is only a draft until it is shown. Another host in the same session may also have changed the prompt.
I cannot start a poll
Turn on Accepting responses, end any current live poll, and check that the poll has two to eight non-empty answers. A single-choice poll must have exactly one correct answer.
I do not see any hosted spaces
Open Invitations from the account menu and check that you signed in with the invited account. See Get access to a hosted space.
I cannot invite another teacher
Only owners can manage access. Use the colleague’s exact Ed.ie username or sign-in email. If you are an editor, ask an existing owner to send the invitation.
The projector is showing old responses
Confirm that the popout belongs to the current session. Remove prompt and time filters, refresh the popout if its live connection was interrupted, and check whether another host changed the shared display settings.
