Service Issues with Channels 48/1048, 66/1066
Please be advised that there are known issues with Channels 48/1048 and 66/1066, intermittently freezing. We are aware of the issue and are working dilligently towards a resolution.
Update as of 06/07/2021: We have engaged the signal provider to resolve the issue and hope to have a resolution for TCM (channel 66/1066) for our members soon. We will continue to investigate a resolution for Peachtree TV (channel 48/1048).
I am unsure if Westman and Bell MTS get their signal feeds from the same provider or not, but it seems that there is only so much that Westman can do, but I could be wrong.
