Bubble has not confirmed whether it will retain the Figma integration that allows importing designs created with iPhone frames. The feature set for the new mobile tool is still being finalized, and further updates are expected once the waitlist moves forward.
If you have designs in Figma, you might need to manually recreate or adapt them in Bubble depending on how the integration evolves. Keep an eye on announcements or reach out to Bubble’s support team for more clarity.
