SecureLine subscription for my PC, can I use w/iPhone?

I purchased a SecureLine VPN subscription for my PC. Will I have to pay for a separate subscription to use for my iPhone? I noticed you can spread an iOS license around to 5 iOS devices, so can I not do the same with my PC?

Licenses are per platform.

avast is working on a cross platform licensing system, but it is unknown when it will come.

Will this cross-platform licensing system be retroactive? Is there an ETA?

I purchased the PC version, under the mistaken impression that I would also be able to use that same license on my ipad. Obviously not the case.
I’ve been a paying customer (Avast Internet Security) for years. Paid for the (PC version) of Secure Line. Now they want more money to let me run Secure Line on my pad.
