I'm trying to upload "app previews" for each size of devices on the ITC (iTunes Connect) and I'm going to freaking out. I really need your help guys.
As Apple asks, I use Safari 9.1.2 under El Capitan to upload my videos on ITC (in 2016 with HTML5/JS that make no sense to force people using Safari for uploading a video... anyway).
Of course before that step I read Apple's specifications and I exported all my videos by respecting their specifications (size, fps, codec, etc.).
One month ago, Apple decided to simplify the "preview and capture" section of ITC because of the increasing number of device and screen size (become difficult to manage). Good idea by the way (in theory).
So I recorded one video preview of my app for each device and started to upload them in each size category. I can upload a preview in his own category without problem until I upload the next one for others devices. Each new uploads for others device erased the last one... I can have only one preview online.
What happens in details:
1)
2)
I repeated the operations several times, in different way/order, same problem all time.
---------- UPDATE - 9 september ----------
I have contacted Apple about this problem and they have answered pretty quickly (less than 24H). You can see below their answer. But this didn't solved my problem...
Another developer had a similar issue. What I would recommend doing is >clearing your browser’s cache and cookies, making all changes needed to >your metadata, and then attempt to upload the App Preview files again
---------- UPDATE - 23 september ----------
I found a tricky solution. Not the best but it works... So my problem is each time I click on the SAVE button, my video preview disappears. EXCEPT if I upload the video previews at the all LAST step. So, everytime I want to release an update for my app, I have to do FIRST all the settings (add a build, change texts, pricing, languages, etc.) then I click on SAVE. After that step, when every settings has been set, I clear all the cache and cookies of Safari, I come back to iTunes Connect, I upload my video previews, then when they have been uploaded, I click on SUBMIT FOR REVIEW... Then it works...

您解释的步骤看起来像是在正确的轨道上。我还上传了不同设备的预览视频。 Apple愉快地接受了所有＆amp;在App Store上显示。您应该联系Apple以解决此问题。

同样的问题......我提交更新，因为预览消失了......
答案 2 :(得分：0)
前几天我遇到了同样的问题。 但我能够避免它。
就我而言：
在上述情况下，出现了问题。保存后，App Preview消失了。
所以，我决定上传每种语言的截图，它运行良好。 我想主要语言的屏幕截图参考是导致问题的原因。
