thank you for the reply.
We checked again, but tabstrip's scroll still doesn't work.
I went to the URL above and checked it with ipad 13.3 OS version, but it still doesn't click the scroll arrow .
I can't publish the working URL because it's a closed network, but I've checked the kendo update but it still doesn't work
I have a video, but it's bigger than the attachment, so it can't be attached, but I can email it if necessary.
