Hi @kgorol,

Can you tell me if this works properly with version 3.7.5 of the plugin?

[kgorol]

Thanks for replying @bd-arc,

Works like a charm on 3.7.5 :)

Still it's not working for me

[calz10]

setTimeout(() => this.carouselComponent.snapToNext(), 250)

adding timeout in the current version works for me :) less than 250 will not snap to next

[pedro-lb]

setTimeout(() => this.carouselComponent.snapToNext(), 250)

adding timeout in the current version works for me :) less than 250 will not snap to next

works for me! thanks :)

setTimeout(() => this.carouselComponent.snapToNext(), 250)

adding timeout in the current version works for me :) less than 250 will not snap to next

Works for me too! Thanks!

I think we shouldn't let this end here...
We have just one workaround, but nothing concrete yet.
Any update coming @bd-arc?

[bd-arc]

@Inovassist-dev I definitely agree that we need to get to the root of it.

The problem is that I need to know first and foremost if this is a bug introduced in 3.8.0 or something else. Hence my initial question.

But so far I've received contradictory answers...

[Inovassist-dev]

Yeah, I understand...
Maybe I can help you! I'll check last versions in order to see if it's a problem in the latest one!
Hope this helps!

Have the same issue running on an iOS device: snapToItem(), snapToPrev(), and snapToNext() don't work.
I spent a long time trying to debug on 3.8.0 with no success, except for @calz10's workaround (which is suboptimal since it adds a noticeable delay).
@bd-arc, downgrading to 3.7.5 does not fix the problem for me. Also not after resetting all caches.
What else can I try? How can we get this to work again?

The problem is here.
When using snapToNext() or snapToPrev(), _snapToItem is triggered again with the old index

Also not working for me on versions 3.2 - 3.8, adding timeout does work, but the fix is far too slow and hacky to be used. Would like to know how this could be fixed as well.

[daaashleywch]

@QQizi any thoughts on how to fix?

[daaashleywch]

@QQizi @kgorol Actually got this to work by removing only iOS check for momentum bug fix here
Now click through and swipe work for me on Android.

@bd-arc I was using version at commit 85980e5 until today and did not have this problem.
I just updated to latest master version (commit 1aebb18) and I am observing this problem. So yes, there is a regression between those two commits.
