@K3vnhill we could use some design input on this
After a donor submits a request to change / pause / cancel their recurring donation, it will go into a queue and be processed at Civi within a couple of minutes. If they navigate back to the donor portal homepage during that interval, should we show something to indicate that their request is processing? It could be a generic bit of text like 'We are processing your change request for this donation' so we don't need different messages for each type of change.
Programming-wise there are some tricky edge cases to consider. E.g. If we just add the change flag to the donation state loaded into the page initially, we would lose it if the donor fully reloads the page before the queue is processed.
