Low coverage area

There is an area on Lost Mountain Rd just north of Bullard Rd, south of Dallas Hwy in Powder Springs, GA (suburban Atlanta) which drops the signal momentarily when you drive through it. The coverage map says it has good coverage. I brought this up around 8 years ago (I can't find that forum anymore) and was told there was a known tower issue and it was being resolved. Now, years later, and switch to 4G / 5G and the problem persists.
