Heather noted here that, “We encourage you to change only if a connection has persistent connection issues.”
I wonder whether there may be a description in the new article or somewhere else appropriate as to what constitutes a connection issue, i.e. is it solely if the connection repeatedly fails to refresh the balance and/or pull in new transactions?
As an example, I have an account that stopped auto-updating and I must manually refresh it, which is very likely a configuration on the institution’s end and not likely to improve by switching aggregators, but I don’t know that for sure, and some users may not know it at all, without it being documented.
