Yes, I had this same issue with timestamp on Amethyst for NostrMedia.com and had to set an acceptable time deviation rule. As for the other errors, mine is both Blossom and NIP-96, but afaik most folks aren't having issues uploading, if you also wanted another sample to test @Vitor Pamplona
Interesting. How big is your acceptable deviation?
I have a feeling that some phones stay a few seconds in the future.
I set it pretty far-future at 5sec. But I think it was only closer to being 1-2 sec off. I should prob scale that back down now.
