After last Update, save an VPN password is not possible anymore

Hello all,

i have here two fairphones. After last Update to 0.16-20210422111920 it is not possible anymore to save the VPN password. We using here from Fortinet the Enterprise VPN Client with IPSEC. I’ve removed everything from the client.
After new installation, if i connected the vpn the first time, i can save the password. But if i open the connection again, must enter the password manually.
Is there some new security feature that is not possible anymore to save vpn passwords?

Very Thanks and best Regards
