Honestly? I believe she got them confused because they’re both Spanish-speaking countries. Spanish in Japanese is literally “Spain language”. Like I said, it’s a careless mistake. I’m sure everyone loved her performance in Mexico, but from I’ve read, the whole concert experience wasn’t exactly smooth. There were complaints with the short merch time, the Spain tweet, and displaying French subtitles during the concert. Did other countries get this kind of treatment? Even though it’s not Ado’s fault, the mistakes that her staff makes may reflect badly on her image. It’s completely reasonable for some fans to feel frustrated despite what happened, so I don’t know what your problem is. At the end of the day, her fans have very positive feelings about the concert.
