My Osmo changed its Wifi name from what I had to something like osmo12345 after an update.   I can't change it back to what I had.  It just keeps locking up when I try.  Any ideas on how to get it to change back to what I want it?  I just had it named Osmo1.  Its the newest version of the osmo +.

Please try to reset Osmo wifi by the steps below and then change again: before powering on, keep pressing the Trigger and Shutter button at the same time, then press Power switch for about 8 seconds, when the right indicator becomes solid green, release them, search Osmo+ WI-FI and input password again.
If the problem persists, you can reinstall DJI Go or use other mobile device to have a try.
