Survey version 2024.2.0 fails to run logic/expressions

I’ve just gone to reopen a survey that was used last year and found as I tried to run it none of my logic and expressions were working. (The survey has some very basic skip to survey complete logic and then a dynamic end URL based on a Boolean question, Survey ID: #bdd13759-88ed-4569-b48b-1b51bac0675d.)

I noticed I now have two choices of ‘survey version’ when running the survey:

in 2024.2.0 none of the functionality works, but running it in 2024.1.0 the functionality returns.

So I suppose I have solved my own problem, but I was wondering if anyone could explain why this is the case?

I have tried other surveys I own with similar set ups and the same is happening, so it is not isolated to just this survey.
