You are not the first guest to complain but this is how the system works.
This has been working exactly this way since July 2024 when LLMP launched. That is why everyone kept telling you to move your Figment or cancel it, and then you would be able to book your Disney / Pixar Films at 9 AM for Nov. 3rd yesterday. This is the behavior of the system once you complete your initial selection, and pay.
The "in park" behavior for modifying a LLMP is different. As was mentioned earlier in the thread as soon as your park day starts at 12:00 AM, the rules change to "in park" behavior. It allows you to have more overlap than the 15-20 minute overlap that is possible in the 5 minute pre-purchase window, and direct "modify" replacement of LLMP times.
No it does not prove your point at all. Frozen was showing as available at 9 AM for Nov. 3rd until just before 10 AM this morning. Please note that Thrill Data is only checking on a polling interval for (1) guest, it is not actual real-time data. They have to use the MDE API interface.
How many guests are you trying to book LLMP for?

Yes -- I never doubted the resolution but questioning why it functions as is. It's odd given it should be enforcing the same 'rules'. I cannot understand why that would be an intentional rule because the end result is the same -- you are able to switch to that same time slot but forcing the cancel is unnecessary. But, alas, it is necessary.

What's the prebook overlap? I am seeing 15 minutes (e.g. 9-10 and 945-1045). I can't squeeze in that overlap anymore right now.
For day-of, does that mean in park would allow 9-10 and 915-1015?
And apologies if I am coming off aggressive just frustrated with the unclear rules that don't make sense. Also, when I said proves my point meaning I do not believe it to be user error but a flaw in the system. From your point of view, I assume you are calling it a user error because you realize the need to cancel. Again, makes zero sense to me but Disney often makes odd choices.
I greatly appreciate the help from all
