There appears to be a problem with the latest versions (unstable and on meet.jit). On web browsers, entering a meeting name will concatenate the strings as usual (disposing of spaces and creating one joint string), but in the Electron app, this concatenation does not happen. So, if you choose a meeting name with spaces, you will end up in different rooms using the browser and Electron app.
For instance, entering a meeting name A B C D TEST:
In the browser, the strings are concatenated as expected to create a meeting ID of “abcdtest”
You can additionally confirm this by checking the invite link generated:
In the Electron app however, there is no concatenation and the spaces are preserved, hence creating a meeting ID “A B C D TEST”:
This can again be confirmed by checking the invite link generated:
I’ve just noticed this issue with the latest versions.
