What do you see instead?\r\n\r\nExpected: roughly the same number of wifis in both sessions. Actual: much fewer wifis on 8.1 than on 7.1 (the number on 7.1 is around 5–10 times as high).\r\n\r\nWhat version are you using? On what operating system?\r\n\r\n0.8.18 (ef93348-dirty) from F-Droid, on LineageOS 14.1 and 15.1\r\n\r\nPlease provide any additional information below.\r\n\r\nScan mode was originally set to Background. In an attempt to troubleshoot the issues on 8.1, I changed it to Full Power mode, to no avail. Will try High Performance next.\r\n\r\nI do not use “Turn on WiFi automatically”, i.e. WiFi should be on permanently."}}
