The final scene from Chapter 5: The Gunslinger (2019) is shown again, but the distinctive sound of Boba Fett's spurs is now missing.
When Boba see's the lights from Din Djarin's flairs (see the Mandalorian S01 E05) he goes to investigate, and discovers Fennec Shand dying (during the same night). However, in the Mandalorian (S01E05) Din Djarin finds Fennec dying the next morning, and Boba discovers her later that night, so a whole day has passed since Fennec got shot when Boba finds her.
Fennec uses a small spy drone with bright red lights on every side, making constant noise, thus being quite obvious. Also, in the scan the drone does, all humanoids are shown moving (and patrolling), but the drone can't have this information of movement.
The bantha appears to be similar to an herbivorous musk ox or woolly mammoth, adapted to extreme cold, but it is presented as a carnivore adapted to living in the daylight heat and dryness of a desert. The thick fur would immediately overheat any animal in that environment. The gigantic bantha would also need large amounts of water and meat to survive, but there is no water in Tatooine deserts and the bantha is too slow to be a hunter, even if there were any animals to hunt in a desert. Likewise, the jaw movements are low-slung, sideways movements of a grain/grass grinder (like a cow or deer), not the up-and-down ripping movements of a meat-tearing carnivore (like a bear or cat).
During the meeting with the family heads, 8D8 is able to translate for the Aqualish delegates. In Chapter 1: Stranger in a Strange Land (2021), 8D8 was unable to provide translation services, prompting Boba Fett to remark that they needed a protocol droid. It is very possible that he was updated with a translation program (would probably be cheaper than a whole new droid)
Boba Fett tells Fennec that he was "left for dead on the sands of Tatooine." He was first left for dead inside a Sarlacc, and when he escaped, the Jawas stripped him of his armor, and he was then left for dead a second time, this time actually on the sands.
When Boba catches the LEP droid, it shuts itself down. However, its arm still moves when Boba is taking it to the trash can to throw away.
Fennec's hair does not fall down in conjunction with gravity when the Slave One is pulled by the Sarlacc.
Boba Fett returns to the Sarlacc Pit in order to retrieve his armor from inside of it. However, Chapter 1 shows him escaping the Sarlacc Pit wearing his armor. It is stripped off him by Jawas later on the grounds of Tatooine, which he notices even if barely conscious. Either way, he must have realized that his armor was stolen. There is no reason to assume that the armor remains in the Sarlacc Pit.
Fennec says to Boba that his beskar armour is likely what saved his life when he fell into the Sarlacc pit (in "Return Of The Jedi") as it protected him from being digested by the Sarlacc's stomach acid. However, Boba does not wear a complete suit made of beskar metal. His helmet and chest plate, and perhaps a few other parts are beskar, but his arms, legs and neck are mostly just covered by cloth. Additionally, his helmet has never appeared to be airtight.
Bib Fortuna (Jabba's majordomo) was on board Jabba's sail barge when it was destroyed in "Return of the Jedi". No explanation is given as to how he survived this event in order to take over Jabba's empire for the last few years.
As the family delegates depart the palace, Boba Fett says of them, "They may be stubborn, but they are not foolish enough to see that the Pykes would eventually take over the whole planet." This would mean that foolish people would see the Pykes will take over the planet, while wise people would not see that. This makes no sense. What he meant was that they are not foolish enough "not" to see that the Pykes would eventually take over the whole planet, which is the opposite of what he actually said.
