I don’t want to give too much information away for obvious reasons but how is the update process able to check a set limit and why would it care anyway? Surely that would be on me to find out why an update failed.
I only ask because this flash message never came up before.
Here is the related issue. The warning is needed because it can cause the update to fail in an incomplete state. I think it only really becomes a problem if you wait too long between updates.
