This film is amazing. Im having a hard time understanding why Star Wars fans dont understand why Kenobi isnt shown at full strength. When Kenobi went into hiding he very rarely used the force to avoid detection. This film does an amazing job showing him reconnecting with the force after years of avoiding it. Its a perfect demonstration of him struggling to regain his strength and connection with the force. Kenobi essentially had to abandon his connection as not to be detected. Even if he could have instantly regained full strength and connection to the force Palpatine and Vader would have easily detected that surge.
