I have just sent a message to the Brazilian Portuguese translator that has the ‘coordinator’ role. Let’s see if they reply to my message. I think indeed suggestions don’t cause the coordinator to receive a notification. Please poke me again here on the forum if you don’t hear from me in a week or so.
By the way: translations that you submitted don’t have to get reviewed in order to land in AntennaPod. Also unreviewed translations will be available when we import the updated texts before a new release.
