Ableton License Authorizations reset – General Discussion

How long does it usually take Ableton team to approve additional authorization or reset authorizations for Ableton Live Standard? I have two Macbooks that has had Ableton License and recently I wiped one of Macbooks of of Ableton software and gave it to my wife. tried to Authorize Windows PC instead of that wiped macbook but I have no authorizations left. So I have just one Macbook with the License. Ableton allows Licensing of two machines. I asked them for additional authorization couple days ago but there is no answer still. How would I remove license from Macbook that I gave to my wife as there is no way to do it (as far as I know). Should I always contact Ableton support to remove licenses of computers in case I replace or sell them?
