Open Figjam session forces login/signup on mobile - works fine on desktop (Professional Plan)

Question

I’m on a Figma Professional plan and have an Open Session enabled on a FigJam file. The session works correctly on desktop - visitors can access the guest name-entry screen and edit without an account. However, on mobile, visitors using the exact same open session link are forced to sign up or log in instead of seeing the guest name-entry prompt.

Steps to reproduce:

1. Open the FigJam file and click Share

2. Enable Open Session (confirmed active, 24-hour window showing)

3. Copy the open session link

4. On desktop: visitor opens the link, sees the guest name-entry screen, can edit with no account - works as expected

5. On mobile (tested on iOS and google phone): visitor opens the same link and is shown a Sign up / Log in screen instead, with no option to continue as a guest

This looks like a platform-specific (mobile web) bug in how the Open Session link is being handled, since the identical link works fine on desktop.

Hey Jodi, thanks for the repro steps and sorry for the confusion this is causing with your open session.

I can see you've already reached out to our support team about this, thanks for doing that. I've added a follow-up note to your existing case with your exact repro steps (iOS + Android, same link working fine on desktop.) for visibility for the team.

Update: Our support team has reviewed this internally with our engineering team.
For others who may have similar request here, unfortunately, we don't support editing FigJam files on small mobile devices (i.e., anything smaller than an iPad). This also applies to open sessions. We’ll pass it along to our internal team for consideration.

For more information, please check and continue directly the conversation directly via your support case, thank you! Sorry for any inconvenience. I’ll go ahead and close the topic here.
