Thank you for contacting us.
As you probably know, we just released an updated version of FOTA WEB tool. While it gives many new features and possibilities, unfortunately, we have encountered some unforeseen issues.
We have already identified the cause and issue should have been resolved by now, regarding tasks not being executed.
For the moment system will be scaled to use even more resources and programmers will work on the system optimization.
These issues might repeat through the week and should be fixed by the end of the week completely.
Task expiration time is 45 days.
Also, can you elaborate regarding tasks not being created when device is moved from one group to the other?
Do you mean if task is assigned to a device and device is moved to other group, task that was assigned disappears?
