Lichess Masters Database Glitching

When I am using the lichess masters database, sometimes it shows this error screen

And when I play the next move, it dissapears, or stays, its pretty random. If I want to see the stats for the position I usually just play a move and then take it back, and by reloading it it usually fixes itself, but it's obviously still a very annoying issue, as you can imagine. This also happens with the lichess games database, and after I did a little testing I saw that it also happens on the same move(s) as the masters one, so they are 1:1 errors just with different database, and maybe its even related with the move/position.
Info for developers: yes I am logged in, yes I tried on multiple devices, yes I also have friends who have this issue, yes is bothers us all. Please fix this as in my opinion its the BIGGEST flaw by far on lichess, thank you for your time and attention.

I absolutely agree, its quite annoying while studying/discovering new lines and suddenly screen just bugs and shows nothing :/ hope it will be fixed soon!

This article is irrelevant to this case, as I am logged in and on a browser, as I stated in the original post. Also I don't really understand what you're trying to say here, sorry

@AndreiFortis67 the problem is

Are there new restrictions or limits, other than being logged in?
No. The access is still virtually unlimited. More precisely, you can send 20 requests per minute, which should be plenty enough.

opps sorry show when arrive 20 requests

@SergioGlorias Oh thanks for showing me this, but when im going through a game fast, and through multiple games per minute, with the masters database open, it isn't enough, 20 requests per minute as for each game 25 moves of masters * 2 = 50 ply so lets say 35 ply/requests on average (as every game doesn't have 25 moves of theory), also, it wouldn't explain how it's fixed when I "reload" the request. Also my friends have been having this and also the guy that commented is having this so maybe its not an issue with the requests/min

Ok I did some testing and it seems that it's indeed this limit, and I used a 60 second timer and checked by going through games quickly vs slowly and tested same positions. That said I think this limit should be upped, as me and every titled player ive talked to about this is having this issue, so maybe the limit should be doubled or even tripled, and I think the service would still be safe from DDoS attackers.

@SergioGlorias Also I dont even know if it sends a request to masters db when it open but its past the 50 plies point, if it did that would be quite inefficient but probably it doesn't, still I hope the limit is gonna get changed somehow if its possible ̧ i hope some lichess dev sees this, as its one of the main reasons I use lichess. The possibility to go through live, recent games, while using the databases to learn more about the opening phase, is a service offered NOWHERE else, chesscom's is bad so I refuse to use it, and no other place combines the two like lichessf
