Dear Piotr,
I hope you’re doing well.
The other day, I asked you about the offline option, but how is it going?
I am worried because I haven’t received your reply since I sent you the last message.
I would really appreciate it if you could deal with the offline option.
If you need further information or more details, please let me know.
I hope this message won’t bother you.
I will be happy if you reply to my message.
Thank you very much.
