Can I be able to signed in to Time Tracker and Manual time from two different computer and for two different clients at the same time? Thanks.
Why would you want to do a thing like that?
How would your clients feel knowing that you are trying to charge them for time spent working for another client?
No, of course Upwork does not allow this and the system will not let you to try and charge the same time to two different clients. There is literally no reason for this being attempted that is in any way OK.
