And after my first upgrade of version from openwrt 18 to 19.07.0 the feature VLANs on "switch0" stopped of work and bricked my router when I try to the action below...
This worked very well before Openwrt 19. I update the firmware to 19.07.2 with hope that this problem was solved but I bricked my router and I spend all morning trying to recover...
I made one work around. I rollback the old firmware, rollback the backup file with one image that this is working and after this I upgraded the firmware to 19.07.2. But now if I change configuration will happen what I showed in the first message in this topic.
So sad. I use this feature a lot
