Not exactly sure what you are saying there (maybe my post wasn't clear) My understanding:
If BizTrip:
1) Had 60 Status Nights in calendar year 2022 then on renewing AP membership on Aug 31 2023 Platinum membership would have extended to Aug 31 2024.
2) Had less than 60 SN in CY 2022 but 40 earned SN in CY 2023 to date then 20 bonus SN given to current AP members in July would have renewed Platinum status
3) had less than 60 SN in CY 2022 and 20-39 earned SN in CY 2023 to date then 20 bonus SN given in July would not have renewed Platinum but when 20 bonus SN are credited for August 31st renewal that should trigger CY 2023 Platinum achievement and bumping back up to Platinum.
4) had less than 60 SN in CY 2022 and less than 20 earned SN in CY 2023 to date then 20 bonus SN given in July would not have renewed Platinum nor will the 20 bonus SN when credited for August 31st AP renewal. Will need to have 20+ earned SN in CY2023 to add to the 40 bonus SN received this CY.

Of course, since no details have been provided (only the SCAM claim) this is all speculation on my part.
