I am also seeing this Amber not installed error. Are your notification timestamps wrong?
The latest version of #Pokey is using Amber, presumably for auth to DM inboxes. It correctly calls Amber, and starts the service after I've authenticated, but it's also throwing up a toast message saying "Amber not installed". nostr:nprofile1qqsxg45ph8gx0vdrvtzta6xal7v86frx6jvstsnvhrlvtehmwwh4epqpzamhxue69uhhyetvv9ujuvrcvd5xzapwvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9nhwden5te0v4jx2m3wdehhxarj9ekxzmny9ua2vh28 any idea of what this problem is? It just an errant toast message? Or do you think there's something actually going wrong?

Discussion
No, my timestamps are fine although I saw some other people had the timestamp issue. I think it's two distinct and unconnected issues. But as much as I'm sad that you're having trouble with Pokey, I'm a little glad I'm not the only one who's having this problem with the Amber authentication failing. nostr:nprofile1qqsxg45ph8gx0vdrvtzta6xal7v86frx6jvstsnvhrlvtehmwwh4epqpzamhxue69uhhyetvv9ujuvrcvd5xzapwvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9nhwden5te0v4jx2m3wdehhxarj9ekxzmny9ua2vh28 here's another user who's having that problem with Pokey v0.0.4-alpha not authenticating with Amber, and the "Amber not installed" toast.
Did you try with v0.0.3-alpha??
I don't have the timestamp problem with v0.0.3-alpha. And since v0.0.3-alpha doesn't authenticate with Amber (other than to pull the npub), there's no process that triggers the "Amber not installed" toast.
In the meantime, I've reverted to Pokey v0.0.3-alpha. All notifications are working properly except DM Inbox notifications. I'll wait til this issue is resolved to upgrade.
