Hello,
Thank you for reaching out!
Unfortunately, there are some issues with the current version of RutOS and WiFi apps when using v7.3 of RutOS.
If the app is important, I'd recommend downgrading to v7.2.8 of RutOS. Otherwise, waiting for an app update is the best option.
We apologize for any inconvenience caused.
Best regards,
DaumantasG
