A full release is on the way, but not until early in the new year, so if you would like a fix, please follow up on the above thread.[/b]
Russ, is this the actual RHP app (appears as 'RedHotPawn Play Chess Online' by netAdapt Apps in Google Play Store) or the RHP Notification Widget, also available via Play Store? I only ask as although visual and aural notifications from the latter work on my handset (new HTC U11, so high-end as you put it!), I don't seem to be able to directly access the website from it. Visual notifications from the RHP app also appear on my phone and I do seem to be able to access my boards as usual.
edit : This update is all about the notifications. There is a very short delay before a move notification arrives after your opponent moves, then a less frequent "Games Waiting" notification if you remain inactive.
Originally posted by @flyingwolf When and how do you want feedback on the Beta test version Russ?
Don't worry - you could either leave feedback here, or even within the Play Store beta system, but after a week with no significant problems that I could see, it was rolled out live.
The issues with Android 8 meant this had to be pushed out ASAP to avoid the increasing occurrences of the crash issue. Next release - conditional moves. This will also have a beta period - anyone already signed up to the RHP Android Beta program will get the update automatically.
