Remote Debugging Tutorial Example Through a remote interpreter stuck with "Pause the process to use command-line."

I'm following the https://www.jetbrains.com/help/pycharm/configuring-remote-interpreters-via-ssh.html#ssh example, and in "Debug your application", when trying to input a value for "a:" (e.g. 3):

When I press ENTER I'm getting "Pause the process to use command-line.", and I can't continue.

When I use the remote interpreter in "Run" mode (not "Debug") I don't have this issue and the program runs as expected.

I've followed this exact manual about a year ago and don't remember encountering this issue. Maybe it is because I recently updated to 2020.1? A similar problem was reported in https://intellij-support.jetbrains.com/hc/en-us/community/posts/360008144320-Console-input-has-stopped-working-in-debugger a few days ago. However, in my case I am able to debug using a local interpreter, albeit the console prompt seems a bit weird (I don't see the ">?" when I use "Run"):

I'm using Ubuntu 18.04.04, and PyCharm 2020.1 Build #PY-201.6668, built on April 7, 2020.

My remote interpreter is Python 3.7.1
