Transaction Search setting in API doesn't work

[sowhatwhere]

I'm unable to activate the Transaction Search permission and retrieve transactions via the API. From the developer dashobard, I've done the following:
1) opened My Apps & Credentials
2) clicked Live
3) clicked Create App
4) Given my app a name
5) Ticked the Transaction Search box
6) Clicked Save
7) Copied my Client ID & Secret
😎 Ran the following (substituting in my client ID & secret):
curl -v https://api-m.paypal.com/v1/oauth2/token \
-H "Accept: application/json" \
-H "Accept-Language: en_US" \
-u "client_id:secret" \
-d "grant_type=client_credentials"

9) Received back a token with the following scopes:
"scope": "https://uri.paypal.com/services/invoicing https://uri.paypal.com/services/disputes/read-buyer https://uri.paypal.com/services/payments/realtimepayment https://uri.paypal.com/services/disputes/update-seller https://uri.paypal.com/services/payments/payment/authcapture openid https://uri.paypal.com/services/disputes/read-seller https://uri.paypal.com/services/payments/refund https://api.paypal.com/v1/vault/credit-card https://api.paypal.com/v1/payments/.* https://uri.paypal.com/payments/payouts https://api.paypal.com/v1/vault/credit-card/.* https://uri.paypal.com/services/shipping/trackers/readwrite https://uri.paypal.com/services/subscriptions https://uri.paypal.com/services/applications/webhooks"

This doesn't work with the transaction search API (gets a "No permission for the requested operation" error) presumably because the returned token is missing the "https://uri.paypal.com/services/reporting/search/read" scope. However I don't know how to get this scope to appear. I've tried creating a new app, creating a dev app, deleting the old token with the /token/terminate endpoint, re-saving and creating a new secret. I've confirmed that the Transaction Search permission is checked. Nothing will produce the required permission. Am I missing something or is this an issue with Paypal's API? Thank you.

Update: with no changes at all, I tried running the same request again and now the reported scope appeared. So it appears to be a cache issue on Paypal's side, which can be resolved by simply waiting.

Having similar issue today, tried to created many apps from same account but doesn't work. 
Been using "Patience solution" for over 4 hours, not sure how long did you wait until got success on retry?

I waited nearly 24 hours before I tried again, so I don't know at exactly which point it was updated. I would just hang on and try again tomorrow.
