Apex legends s13 arena’s glitch(es?) shop closing exploit.

Played on Xbox during season 13 second split, I’m guessing it works on ps too don’t know about pc. The glitch: whenever you buy the exact amount of materials you have, it automatically closes your shop and everyone else’s. 2nd glitch maybe?? The 2nd round, I buy the first upgrade to a flatline at the last second and still have my points. Yes I did it in rank not to exploit it but because I was already grinding ranked and too lazy to switch to pubs. No I didn’t reach diamond from doing this. I lost more points from getting silver teammates don’t worry. Please ‪@Mokeysniper‬, you have a louder voice than a casual, can you also add fix ranked arena matchmaking too
