As I would expect, when I begin to enter a command in the console, a menu of possible auto-completions comes up. If I choose any of those options, the command pops up, but the first letter repeats.
Example: If I begin to type libra, library pops up as the initial choice. If I then hit enter, the command line reads. —- llibrary() —- i.e., the first letter repeats. So far, this happens uniformly. I am using rstudio cloud on Safari on an iPad.
The same problem happens on Chrome - but in addition, the command line disappears completely on Chrome. It is completely unusable.
