AirPods Pro No Location Found

Everything were perfect, find my too, until I left my left and right AirPods without charging overnight. So I got one of them seems not charged the same as other one after I insert them both for hours. I started trouble shooting by reset the AirPods and repair agin so the charging issue was solved. BUT I started to have problem with "Find My" by getting the message "No location found". I checked my iOS that is up to date. Remove the AirPods from my Apple ID and repaired again but "No location was found" is always there. Is there anything I can do with? thank you in advance.
