Recently launched METV Toons OTA channel 18.9 out of Charlotte NC does not show up in guide so that I can watch it. 18.1 thru 18.8 work fine. 18.9 was there until Thursday June 27. Just disappeared. The channel scan says 82 channels are found, only 81 appears in guide. 18.9 is the missing one. Re-scan, reset or anything else makes it come back. I know it is available to me because 2 Samsung TVs connected to same antenna will show that channel. What am I missing?
