R5 + EOSR adapter w/ ring + EF 100 2.8L = can't auto focus close up?

The lens auto focused at 12 inches mounted on a 5D3. Cannot auto focus closer than about 18-20 inches on the R5 with this setup. Sometimes works with spot but still hit or miss. Do others have better luck with AF in this setup?

Canon EOS 5D Mark III Canon EOS R5
