For me, it works sometimes. Really, it’s just a terrible app.
Audible help say there are no known issues!
I’m convinced it’s a problem with the upload being damaged or incomplete even when it says it is ok.
This is at least in part because over Bluetooth it takes so long but also because I’ve tested and the app on the phone says it’s complete when it absolutely isn’t- because I haven't even had the phone on. Sometimes you get an error message and its says it can’t find the phone but sometimes it says it’s worked ok.
I still feel using the option to send it in parts helps because it’s less likely to get corrupted, but it doesn’t always help.
Also, it’s much better if you can upload over wifi but that doesn’t always work either but it's much faster and much less likely to break down. When the upload stops then it has to find where it was to start again and I think that maybe the problem. Something I thought we had done away with +20 years ago, but I think that's it.
The way to do this on wifi is to start to synch over Bluetooth and when it’s going, then turn off Bluetooth on the phone in settings (it must be in settings) and after a couple of minutes if you are lucky, it’ll pick it up in Wifi and complete the upload in about 10 minutes. or even less. It still likes to be on charge but you might get it to work without.
The phone and the watch have to be on the same wifi network.
After it’s uploaded, it should be accessible straight away but if it isn’t you can reboot the watch and it’ll pop up.
However it’s more than likely that the file is damaged and the controls won’t work afterwards if it doesn’t work straight away.
If it doesn’t work, the best thing is to delete it and have another go. It might take 2 or 3 goes. I’ve persisted this way and got a book to work.
It also seems to help if you haven’t started the book on the phone. I’ve never managed to get it to work on the watch so far if I’m ever at any place than the start to so maybe that’s messing it up too? Just what I've found for others with no problems, this may well work perfectly.
It is also a good idea to delete it on the phone if you have started then redownload and go straight to synching. This worked for me once when I couldn't get it to work.
If you’ve got it working and it freezes closing the app should fix that.
You do this slightly differently depending on your watch model (and I’m not an expert) but they all involve pressing the power button and then some manipulation like sliding the app screen that appear across to shut it down. I think on some models you press the crown after : you probably know on yours.
When you start it again the controls should work again if they worked before. This doesn’t help if they have never worked however.
I have never got the controls to work paired to any other headphones either. AirPods, yes but nothing else for me.
We are all really trying to make sense of this. I post this not because I’m sure I have a solution but in the hope it helps a bit and maybe leads to a better solution from someone else.
It may also be linked to a particular version of the watch too considering the way to shut an app is slightly different there must be differences.
Mine is a 5.
Good luck everyone.
