Developing flexibility with hypermobility

Hello! I recently learnt that I'm hypermobile; my hips, ankles and knees being the worst. I'm doing light stretching every day and 2 x intense stretching routines a week. 1 of them being at a flexibility class. Despite being hypermobile, I'm not that flexibile.

Any middle split training is hurting in the tendons of my pelvis even if I feel like I'm microbending or tightening the muscles instead. My knees keep giving way when practicing front split and I'm overall just in a lot of pain through the week, but not in my muscles (I did originally but less now. Assuming that was DOMS). Its always in my joints.

Any advice on developing flexibility whilst being hypermobile would be greatly appreciated!
