Unable to login via webos browser

[ArnoldMo]

Good day,
I am unable to login via webos browser, but I can login via chrome,

what I tried:
Only Local Sign-In, Only Jellyfin Sign-In
from the WebOS browser disable Adaptive Straeaming using Javascript and Use Block Ads
when I used plex, I was able to login via plex login

WebOS: 6.5.3-47 (kisscurl-koli)
Web Browser: @87.2.69.mlt4tv.submissions/87.2.69.mlt4tv.211_@299.mlt4tv.submissions/299.mlt4tv.200

Webos browser is probably too old. We don't support tv browsers anyways
