Shelly extender modus and esp-01, not able to find network

Hi,

I activated the range extender modus on a shelly device and configured my esp-01 to connect to it’s ssid however the esp-01 is not able to find the network, it doesn’t appear in the list, is the name maybe to long (no way to change it apparently)? I also tried it with the fast connect option enabled but still no luck

Apparently it’s something to do with the esp-01s, I flashed the same firmware onto a regular esp and it does find the network…
still the question why he picks up other networks

No logs = no issue.
