Razer Theme Store App will not download ... Is there any alternative action ?

Hi all. My razer phone 2 required a factory reset so having backed up to Google this was done. All required apps have been reinstalled and permissions checked. I can open Razer Theme Store app but it takes me as far as download (my chosen theme) but at that point I am given an error message "unable to download, please try later". This app can not be uninstalled and reinstalled as it is part of the OS (Razer Android 9). Any ideas on how I can change my theme while this issue exists ? Cheers, Ross.
