A glitch about crossplay matching system - Apex Legends for Nintendo Switch

Product: Apex Legends
Platform:Nintendo Switch
Please specify your platform model. Nintendo Switch
What is your gamertag/PSN ID/EA Account name? MotionGlider
Please provide your squad mates' gamertag/PSN ID/EA Account name if possible. -
Are you using any software with an overlay? No
Which Legend were you playing (if applicable)? Valkyrie (doesn't matter)
Which Legends were your squad mates using (if applicable)? doesn't matter
Where did the issue occur? In a match
Which part of the map or menu were you in? If you don't remember the exact name, please describe the area or what you were trying to do in the menu. doesn't matter
What were you doing when the issue occurred? E.g. respawning a squad mate at a beacon, using an ability, a squad mate left the game. just normally playing Apex
Did your squad mates also experience the issue? Yes
How many matches had you played in a row before the issue occurred? doesn't matter
When did this happen? (dd.mm.yy hh:mm) It could happen everywhen because it can be deliberately demonstrated.
How often does the bug occur? Often (50% - 99%)
How severe is your issue? Major impacts to gameplay
What happens when the bug occurs? Players on other platform than NintendoSwitch get into the match, even when we disable crossplay matching. They are mainly PS4/PS5, but I've heard there are some ways also for PC to get into Switch match and seen only once while playing.
What should be happening instead? There should not be any PS4 players.
Steps: How can we find the bug ourselves? There are several ways to judge whether a Switch player or not: ●Name - Switch players can use 10 characters or less for username. If username has 11 characters or more, it is 100% a glitchuser. - Kanji or Korean character are not available so if username contains these kind of letter, it's 100% a glitch user. ●Badge, Trackers, Skin etc - APEX Legends switch ver was released when Season 8 started, so when players have something we can get only before S8, they are glitch users. (Possibly Switch players might get these weapon skin from death boxes) ●In the first place... - Now we can turn on crossplay matching also during the match, so by doing this we can exactly know opponents' platform.

 I really beg your help. Today Apex Legends on NintendoSwitch is full of glitch users. Players on other platform can get into Switch server even we Switch players disable crossplay matching. Actually an easy glitch (very very easy to demonstrate) enables them to invade Switch APEX.

 EA has ignored this serious situation since S12 (more than a year ago). Now we find many PS4 players anywhere, regardless the playmode. In trios, in rank match, and even in control. The situation is especially bad in rank matches above Diamond. Maybe none of matches have no glitch users. Also I've seen glitch users trying to get badges like wrath or wake, in trios. As you know, NintendoSwitch has much lower performance than PlayStaiton　or PC. Don't you think that platform-mixed match can't be fair??

 I report them whenever I find, but I never feel it's effective. You never tackle this problem, never punish glitch users, so the number of them is not decreasing at all, but rather increasing. Glitch users are about to completely fill high-ranked preds list on PS. Why do you do nothing? How dare you abandon us for really long time? Glitch users feel no guilty and get cocky, and we can't do anything but can only complain, which is quite pointless. I don't think this is acceptable. Did we do something bad? No, it's glitch users that are 100% guilty!

 Here is my suggestion: I think the number of players on Switch is much less than those of PS4 (I don't know exact number, but you do), so naturally thinking, it's strange that there are a few PS4 players and many Switch players in a match. Can you introduce the system which works when a situation is like above? Also we need other solutions for Arena or Control.

 Anyway we really hope you fix this glitch. We just want to enjoy this game! I don't want to fear PS4 invading us anymore. Please...🙏
