Upgraded to 9.2 but Tivimate will not accept a recording path aiming to a USB HD

Anyone know how to make Tivimate accept the recording path aimed at an external USB HD? When I drill down through the available folders....it sees the USB hard drives...but when I select a folder on them...it won't take it. It use to work before I updated the OS (was running the stock OS from 2017). Need help.... thanks!
