EA Play Pro can I use my account on PC & Xbox & PS5?

Hi, the clue is in the title - I own a PC (well two PCS - a home Rig and a gaming laptop, an Xbox Series X and a PS5! (too much time on my hands clearly :-p).  I currently have EA play with my Xhox ultimate membership which comes with I can use on both my PCs and Xbox Console.  I'm looking at upgrading to Play Pro  so I can play your new releases when they come out and try some of your older titles that ive missed from the last 7 years (I didnt start gaming again until the pandemic forced me to be house bound!), I was a pro gamer back in the early competitive FPS PC days and now im back! Is there any time limits on the new games play time on Play Pro? Play pro seems perfect for me as I like to test all new games but will only get time to play them for a short time each one, so the burning question - would my Play Pro work across all my devices? If not which ones? And also if not is there a membership option which would allow me to do this, or do I need to buy separate ones for each platform? Thanks!
