I'm attempting to use nostr:nprofile1qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcppemhxue69uhkummn9ekx7mp0qqsrc23txhhfq2yt9m32s7h90864j2cg62hvq4tpkrz8cvhpg5z39vgh9talj but the Buy option is greyed out and gives me a "buying is temporarily unavailable" message. This has been going on for at least a few days. Anyone else experiencing this?
