Apple Search Ads - 503 service unavailable error on fetching “acls” endpoint.

Hi team, Kirill Zharskii from Fivetran engineering team is here with a question related to Search Ads API.

Several of our connectors are facing an issue trying to fetch acls endpoint:

curl -X GET -H 'Accept: application/json' -H 'Content-Type: application/json' -H 'Authorization: Bearer <BEARER_TOKEN>' -H 'X-AP-Context: orgId=null' -A 'Jersey/2.45' 'https://api.searchads.apple.com/api/v5/acls?limit=1000&offset=0'

the response is 503 service unavailable, but the request for token works fine.

the issue started about 12 hours ago and going on.

could you please share some input?

TIA
