EXTREME DELAY DURING CHAMPION SELECTION

For the past 2-3 days (since tft mode came out I guess) I get huge delays when I go to ban the champ I want ,like I cannot click no matter how hard I try,but it doesn’t happen all the time.But now,2 champ selects in a row,I could not ban due to lag and then when I clicked my champ to lock in,it disappeared like they banned it or picked it but none of those 2 happened so I continued clicking and clicking afraid Imma get dodge timer .I could not lock in and I got kicked out and got 4 minute dodge timer.Then right after that I tried again after 4 minutes and the same thing happen and now I have to wait 14-15 minutes.Does this happen to you too?It is not a P.C. problem,gameplay is fine,it’s just this very annoying thing so I think it is a bug.Will they do anything about or they don’t know it happens?I guess other people reported it too but it’s been 2-3 days and idk...It is very annoying especially after what happened this time.
