When I propose an alliance, it shows 2 pending proposals with delete buttons next to each: World of War[WoW] and [WoW]. So it could be related to this.
It looks like I can send and receive more than 1 aid package per day?
There's no link to get to the alliance page on mobile for classic theme.
It would be helpful to show which nation member did alliance related things like send aid package or propose/end alliances in local news.

Edit:
When I click to send an aid package, the popup says: Are you sure you want to end this alliance? Then the alliance ends
But when I tried this again with my other alliance it works. So I don't know what's triggering the first message.
When I try to send more than 1 aid package, the error message repeats itself.
You can only send 1 Military Aid Package to this nation per 24hrs!

The cap of 1 aid package per day works for military but not money.
