Other people can't hear me

Please make sure that your browser allows your microphones and that they are not muted.
If the mic button doesn't work, the microphone is blocked in your browser settings. Please allow the microphone in your browser and connect to the room again.
If you are unable to connect even after allowing microphones, the communication may be blocked due to firewall settings in your office or campus network environment.
In addition to ports 80 and 443 for general HTTP communication, ports 51610 to 65535 for TCP/UDP need to be allowed.

Because of these various factors, we currently do not specify the recommended specifications.

Rooms are not transferable. This is prohibited by the Terms of Service.

I want to adjust the volume of the video placed in the room.

When you place the cursor over the video, the volume control buttons will appear.
Set the volume to 0 to mute the sound.

URL thumbnails and Japanese characters in PDFs placed in the room are garbled.

Japanese cannot be displayed because multibyte characters are not supported.
By placing another image on top of the thumbnail, you can press the link without losing its appearance.
In the case of PDF, please use a file printed as an image to avoid garbled characters.

Items placed in the room go to the other side of the wall and cannot be moved.

After the update in October 2021, it may occur depending on the settings when outputting 3D models.
