TS Connection while concurrently using 3rd party VPN.

Talescale is set up and running…so cool.
Running into an issue where switching to TS VPN requires disconnecting from 3rd party vpn.
Desktop seems to have no issues playing nice w/both TS IPs and VPN. On the iOS devices, well it is a right PIA to be always having to switch connections depending on the task at hand. Even exit ports would have an issue as the desktop would need to be connected

What are the options to stay connected to TS while using 3rd party vpn anonymizers on iOS?
Split tunnes, proxies, exit port…?
