regarding of support of RALE

is the support of roku advance layout editor not working , when i open it showing this error. Kindly help and tell me any alternative.

I had the same problem. I solved it by changing in roku device in Settings, advanced system settings, control via mobile apps. There you change it to Enabled and that’s it.
