I noticed a strange behaviour in the Google API Console. I added an IP Adress restriction on a server key and everything worked fine: the restriction was behaving as expected. However I afterward tried torevert back to the "no restriction" situation. The console did not show any error and the restriction seems removed (I have again the yellow alert notice), however the restriction is still blocking the Google cloud messages I'm trying to send from a previous unauthorized IP adress.
For instance I cannot simply add the new IP adress, since it may vary.
Do you know if I'm doing something wrong?
