Web timeout far too short


When I’m doing my accounting I’m at my desktop switching between tabs of Tide and my accounting software. Far too frequently I get kicked out of the Tide Web interface and have to login again using the phone.
I’m much more likely to be doing complex business work on the desktop than the mobile so this is highly inconvenient.
Even the old-school banks don’t timeout that frequently any more.
Please don’t log me out until I close the tab (or if there must be a timeout, something like an hour)
