If the error message "PayPal is temporarily unavailable" appears in Gambio GX3 when attempting to pay with PayPal, and the logs contain the message "Error creating payment resource for ECM payment: ERROR creating payment: INVALID_EXPERIENCE_PROFILE_ID The requested experience profile ID was not found", this is due to incorrect backend settings in the PayPal PLUS module. The "Display on the PayPal payment page (PayPal parameters)" setting should be checked or adjusted under the expert settings.
If no profile / presentation exists, it must be created and used (in the languages being used). Done.
