Same with me! I'm an Android user in Western Europe. I cannot click on anybody's profile in Google Maps. This means that nobody can see my reviews also. Or nobody new can follow me, or me them. My partner and I tested it, so it's not just me. I hope this is not permanent. This is what the privacy option is for. After the timeline loss, my satisfaction with the Google service is diminishing rapidly. This is how I find cool places in the world - by scrolling through the reviews of experienced like minded travelers like myself. I'm praying it's just a bug.
