Merchant not initialized anymore

[tkocik92]

I am using the PayPal Here SDK with the Sandbox environment and had it implemented in my application for over a year. At some point in the last month, calling RetailSDK.initializeMerchant no longer initializes the merchant after login. The account I used worked previously. The only relevant logcat messages I can find are the following:

E/PayPalRetailSDK:paypalRest: Received error (domain: auth, code: INTERNAL_SERVICE_ERROR, message: , debugId: 6b23e169c1791, details: )

The version of the SDK I am using is 2.1.0.201801

Is there an update I am unaware of to get things working again?

Closing this issue as the problem is no longer occurring despite not making any changes.
