We didn't have a problem with Figma's technology, but we did have problems with their UI. For example, it confused "teams" and "projects," making managing your work and granting access to people a baffling pain in the ass. It took a week of E-mailing people for me to gain the necessary access to my own team's files when we adopted Figma, most likely because of the inept segregation and presentation of these entities.
Has there been any UI overhaul since acquisition?
