Orbot VPN mode enabled-apps ignoring

since the last couple of days i have encountered a little problem.

on my devices :
- HTC one m8 + lineage for microg (14.1-20190111-m8)
- Samsung s7 edge (unkonown)

out of the sudden the vpn mode stopped working

logs (swipe from right to left) says 100% bootstrapped...

tor browser(org.torproject.torbrowser) and orfox(info.guardianproject.orfox) do work
check.torproject.org returns "congrat..."

but vpn-enabled firefox,chrome,duckduckgo,... seem to bypass tor-vpn
check.torproject.org returns "sorry..."

already tried reinstall and older versions - nothing helped

orbot versions : f-droid :
16.1.2-RC-2-tor-0.4.1.5-rc (first starting to bypass)
16.1.0-RC-2-tor-0.4.0.4-rc (downgrade 1)
16.1.0-RC-1-tor-0.4.0.4-rc (downgrade 2)

i didnt update system or other relevant apps - just at some point it stopped working
