"Bug or feature" of speed setting on meshtastick 433 MHz?

Hello gentlemen, developers!
Recently I purchased modules TTGO Lora32 for the 433MHz band to check the coverage of the terrain with a signal. I tried uploading several of the latest firmwares to the boards and I just found the same error. This is the impossibility to change the data transfer rate in the specially designed tab of the phone. Any attempt to change the speed results in one #longslow scenario.
Is it really such a “bug” for the 433MHz band or specially introduced restrictions?

ooh - sounds like a bug! can you create one on meshtastic-android and link to this thread?

I duplicated the theme in the Android theme.

heh! I think I was unclear. No worries - I just created the bug on github:
