When using Gamma's AI to generate a PPT, a Korean character suddenly appeared in the middle of a section of text, disrupting the continuity and readability of the entire text.

A manufacturing company's critical production system was infected by a ransomware virus, which shut down the entire production line for a week. The company did not do a good job of system patch updates and employee security awareness training, making it easy for the virus to “infiltrate” the internal network. The accident caused huge financial losses to the company and seriously affected the delivery of customer orders.
