Custom User Properties Not Updated

[3a4or]

I have A feature flag on my Amlitude portal and I added a segment with custom user property to this feature flag so it is on or off depending on this segment, the problem is the feature flag is always on even if I change the value of the user property to makes the flag off.
For more clarification find the following example:|
I have a feature flag called "new-feature" with a segment where it's a custom user property "isNewFeatureSeen" is none, this means this flag will be on for any user that didn't change the value of "isNewFeatureSeen", now I changed the value from my Android app with the following code:
val eventProperties = JSONObject().put("isNewFeatureSeen", "yes")
Amplitude.getInstance().setUserProperties(eventProperties)
Amplitude.getInstance().identify(Identify().set("isNewFeatureSeen", "yes"))
Amplitude.getInstance().logEvent("sync", eventProperties)

after calling this code the feature flag "new-feature" was supposed to be off the next run of my Android app but it always returned on and sometimes after waiting too much time (between 2 to 120 mins) it returned on as expected, so this strange behavior and I don't know where is the problem, so any help about this?

for more information:
my Experiment builder is:
ExperimentUser.builder()
.userId("my userId")
.build()

My ExperimentClient:
initializeWithAmplitudeAnalytics(context as Application, "my key", ExperimentConfig())

thanks in advance and looking forward to hearing from you soon.

Hi @3a4or, could you provide the following information so that dive deep into what was happening there:

• to confirm the identify event was actually sent, could you share the link of your workspace, a link to a user profile which has sent identify and sync events
