Tier 2 Extension implications of time spent outside UK

Hi All,

just wanted to check if anyone has any answers for the following.

My Tier 2 Visa was granted to me on 1-09-2020 successfully. Since then I have spent a lot of time overseas due to many reasons (partners health, getting stuck overseas due to covid, holiday). This accounts to nearly 5-6 months.

I have just submitted my visa extension application (CoS assigned, application sent, IHS paid, biometric appointment booked etc) ... I wanted to find out if there will be any implications for me spending so much time out of the country whilst having a UK Tier work visa; i.e. can my extension get declined based on the above ?

I know that eventually there is implications when applying for ILR (spending more that 180s outside in a year) but will there be any for an Tier 2 extension ?

Please help if anyone has knowledge on this; I cannot find any info online

just a further note; my extension application was made whilst I was in the UK (not overseas)
