Thank you for your help, I'm very new to this. I reverted the changes and edited the tags as you proposed.
I removed "brand" since they only have this one shop and the tag didn't seem useful in that case. I also set "operator=High Standards Auns" since they use that name in the legal notice on their website. I didn't update the survey date, since I'm not sure if all the other tags are still valid, but I kept them. If you want something changed you can do it yourself or comment on the new changeset: changeset/179555143

Sorry, i mistook the change you meant. In this case the shop had changed. So when Street Complete asked if IT still exists I answered No and then entered the name of the new shop. I think this led to it being deleted and replaced with a POI with the new name but empty tags. Would the better way to edit it be, that I just change the name, because it is still a shop for Cannabis products. Or would it be better to keep this change, because with the new name the owner might have changed and therefor also properties of the shop, which would invalidate the tags associated with the previous shop.

Hi,

I did this through Street Complete. It asked, If this place was still there and I Just answered "Yes". I didn't intend to deleted anything. Can or should I just roll this back?
