you can set when it can be activated and when it can't
read the documentation
there is alot of great explanations there

but cant you just do that with UIS and a bit of logic
not that much even
yea you can but CAS can also be used to create mobile buttons if i remember
i also dont use CAS alot
oh
tbh i feel like UIS seems like everything one would need but
im kinda curious what it has if they went out of their way to make an entire new service
bro i use cas more than uis

Is Roblox sunsetting CAS?
Yes, we plan to sunset CAS in the future. Sunsetting means that your existing code will continue to work, but we will not make any changes to functionality, effectively deprecating the API for future use. All functionality that CAS supports will be supported by IAS before we sunset it. If you use CAS, we highly recommend migrating to IAS.
