I’m having the same problem right now! I solved it by running this SQL query.

CREATE TABLE `tabSessions` (
  `user` varchar(255) DEFAULT NULL,
  `sid` varchar(255) DEFAULT NULL,
  `sessiondata` longtext,
  `ipaddress` varchar(16) DEFAULT NULL,
  `lastupdate` datetime(6) DEFAULT NULL,
 /* this next line is not being applied for some reason. */
  `device` varchar(255) DEFAULT 'desktop', 
  `status` varchar(20) DEFAULT NULL,
  KEY `sid` (`sid`)

I upgraded to frappe v14.39.0 and it seems frappe is dropping support for mobile therefore removing this distinction. idk why migrating doesn’t show this.
