“testflight the requested app is not avaliable”

I did a resync and it worked for me:Go to the Apple Watch app on your iPhoneGeneralResetReset Sync DataWait for a few minutes and it should come back up.

I tried it with Directv, Starz Play, HBO Go, Encore, Netflix, and Youtube apps none of which worked !

I've noticed everything seems a bit snappier as well and there are several apps I've noticed that seem to just work better. They display faster, scroll better and just overall look better even without any upgrade to the app so far.This beta, at least to me, seems to be much, much less chaotic than previous ones with the only issue I've found so far being the phone app doesn't work unless I'm using a bluetooth headset. I can answer the phone or place calls but there is no voice when using the handset directly.

I was thrown off by the WatchKit App terminoligy used, too. I was expecting there to be a watchOS app option. But the WatchKit app selection is what you want.All watch apps linked against watchOS 2.0 will install the Watch Extension on the watch vs on the device. Here's a link to the relevant transition guide:watchOS 2 Transition Guide

The phone software seems very solid so far, and I'm running it on an iPhone 5. A few tiny display glitches, no 3rd party apps with issues. As fast or faster.The watch software seems extremely slow and I've run into some pretty serious bugs already. Unlock keypad staying on screen overlayed on watch face. Pushing digital crown in doing nothing (stays on watch face). Can't get debuggin on watch to work. Notifications from Messages don't seem to come through (more testing needed).

That appears to be the case for as well, now that you mention it.I only really use iCloud for Messages, Contacts, and Calendar. Messages seems to be separate so that works, but no Contacts or Calendar, Calendar is the biggest hiccup. I don't change my contacts too often. I'm assuming something like this would be fixed in the Beta 2, seeing that its affecting almost everyone.

These third party apps will need to be updated to support the feature.

HI :1) Abandoned BatchWe found that while you have submitted In App Purchase products for your app, the In App Purchase functionality is not present in your binary.this assume that you don't have an article in ITC for IAP ? you can't use IAP if you don't create articles on ITC2) Missing restore mechanismYou have to implement a restore Mechanism, but if i refer to 1) you don't even have IAP configured for your app...??i just assuming, i don't know your project... ^^

Works fine when using videos app or even HTML5 videos in Safari

Well, first you need to decide what you should put in different places. ie: watchos2 requires a different way of thinking. What are you calculating? If the inputs for the calculations come directly from Apple Watch, then it is much better that the extension runs on Apple Watch itself. If the inputs do NOT come directly from Apple Watch, you may think about doing calculations in parent app in background (or even on a server) and using WatchConnectivity to send them to Apple Watch from the parent iOS app.For instance, we (at Mouseaddict) track where the user goes inside of Disneyland when they are visiting. This type of data can be displayed on Apple Watch in a glance or watch app. (it does not now, but it could). This would be perfect for running on the parent app because the datam we are crunching does not come directly from Apple Watch itself - it is lat/lon and the phone provides that because Apple Watch doesn't have a GPS. Hence this should be crunched

You can still build a test your app on 2 and then submit using Xcode 6. I run beta iOS updates and then build production apps with the old Xcode - you don't need a device plugged in to do this. However you're risking missing bugs as your test OS doesn't match your build OS. As for switching between watchOS 1 and 2 - downgrades are not supported or reccomended.
