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.

I also was not getting timestamp errors on 0.0.3-alpha

Yeah, Timestamp problem is already identified. I'll try to do some combinations to see if I'm able to reproduce the Amber thing
