Speedlite RT radio sync problems

Hullo, I recently aquired a Speedlite EL-5 and was thinking of pairing it with the ST-E10 transmitter for off-camera flash. I found dozens of complaints online that since a couple of years ago, the Canon RT connection drops constantly and is unusable, probably due to interference. Does someone have a good experience with the radio sync? Apparently a lot of people are having problems - are there any who don't? This situation is the best advertising for Godox, really thinking of returning the Speedlite for the V1 Pro - that in itself would be inferior to the Canon, but with excellent compatibility and radio sync!
