Mount Thunderbolt 2 drive in 2021 MacBook Pro M1 Max

Hey, anyone else having real problems mounting a Thunderbolt 2 drive on a MacBook Pro 2021 M1 Max using a Apple Thunderbolt 2 to Thunderbolt 3 adapter? I don’t enjoy getting my Promise Pegasus or G-Technology Shuttle XL TB2 drives to mount. They light up when connected but nothing is displayed, not even in Disk Utility. This setup works perfectly on my 2018 MBP, so I don’t think it’s a bad adapter. I’m on Monterey 12.0. Any ideas / suggestions would be greatly appreciated. Cheers
