After updating to firmware version 9, I noticed a delay in all control inputs, including the keyboard and controller. I didn't jailbreak yet. I tried various devices, but the issue persisted. The PS4 Pro took around 5-7 seconds to respond. I attempted several methods to resolve the problem. I performed a hard reset on the PS4 and reinstalled firmware 9 (obtained from different websites) in safe mode, but none of these attempts were successful. Previously, everything worked fine. I don't wanna update above version 9
