I'm not sure about how popular is iwd among Siduction users, but be aware that libell0 update breaks iwd and might leave you without network connection (if you were like me and got rid of wpa_supplicant...)

No problem with iwd=2.21-1
This is the actual version
Indeed, I can confirm that fresh upload of iwd mitigates the issue
