This problem started today; it didn’t happen before. Many times, it just doesn’t recognize the changes made to the files and gives the “No changes to commit“.
The workaround I found is to edit any random file and try again.
We shouldn’t depend on such workarounds, should we?
brutal, thank you for warning us 
Happening to me too the last few days!
EDIT: After I check my github repo it shows the updated changes even though it said no changes to commit.
Hello @aroshidze
Thank you for reporting this! I’ve confirmed the issue on my end as well. I am escalating this to the internal team.
Same problem. So frustrating. Comment box is empty Files are there and unable to commit. Please fix this Google/Github.
The issue is persistent with rollbacks too if you go to an older version of the app
