Arduino IDE claims upload did not work, but in fact it did. (Same thing happens with PlatformIO.)

Hi,
I'm a brand new Teensy 4.1 user and this is my first afternoon trying one out. I am running on Ubuntu and have PlatformIO with VScode installed as well as the Arduino 2.3.2 IDE with Teensyduino installed. I tried uploading a simple blink program. It seems to require me to push the program button in order to upload code. The code I am trying to upload actually does blink the LED with the pattern I programmed. When I upload, I get this message on the Arduino IDE:

```

Unable to open /dev/ttyACM1 for reboot request
Often this error is caused by ModemManager mistaking Teensy for a modem.
Make sure you have the latest 00-teensy.rules, or uninstall ModemManager!
Teensy did not respond to a USB-based request to enter program mode.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
Failed uploading: uploading error: exit status 1
```
If I look at the log in the Teensyduino window and ask for Verbose Information, I get this:

Is it supposed to just program without pushing the program button? Is there some way to get the Arduino or PlatformIO IDEs to tell me the truth?
Thanks,
Rob
 
It seems to work for my friend who is using Windows, so it is something to do with my computer which is running Ubuntu.
 
I just tried again and now it works just fine. I don't know what was wrong before. I did update, and possibly reboot between the last try and now. I noted before this Teensyduino window didn't just appear like it did now when I tried to flash. In fact, I thought maybe it just appeared for Arduino, not PlatformIO, but it appeared in PlatformIO just now. It flashed without pushing the button.
Thanks to whoever fixed it!
